  • Tailoring Nanochannel in ZSM-5 Membranes via Al Distribution Control

    Motomu Sakai, Saki Moriya, Rina Matsumoto, Takumi Kondo, Masahiko Matsukata

    ACS Applied Nano Materials    2024  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    The effects of Al distribution on the permeation and separation properties of the ZSM-5 membranes were investigated. Two types of ZSM-5 membranes with different Al distributions were prepared via secondary growth methods using pentaerythritol (PET) or tetrapropylammonium cation (TPA+) as organic structure-directing agents. The results of 27Al-NMR and UV-vis-DRS suggested that the distribution of Al in ZSM-5 membranes can be largely controlled in the channels or intersections using PET or TPA+. Membrane properties were evaluated by conducting hydrocarbon vapor permeation tests in unary systems and a separation test for the methanol/H2 binary mixture. Significant differences were observed in the permeation behavior of the n-alkane hydrocarbons through the two Na-ZSM-5 membranes. The activation energies for the permeation of n-hexane through ZSM-5 membranes in which Al was mainly located in the channels and intersections were 46.8 and 18.7 kJ mol-1, respectively, indicating that Na+ in narrow pores would disturb n-hexane permeation. In addition, the separation performance for the methanol/H2 mixture considerably depended on the Al distribution. The separation factor was massively improved by the maldistribution of Al in the channels, possibly because methanol adsorbed on Na+ paired with Al in the channels blocked H2 permeation, resulting in high methanol selectivity.

  • One-Pot Synthesis Method of MIL-96 Monolith and Its CO2 Adsorption Performance.

     View Summary

    A novel preparation method was proposed for a metal-organic framework (MOF) monolith using a simple one-pot synthesis method. A MOF tubular monolith was successfully prepared by the hydrothermal treatment for an α-Al2O3 monolith in an aqueous solution of 1,3,5-benzenetricarboxylic acid and nitric acid without the addition of a metal source. The effects of temperature and the HNO3 concentration in the synthesis solution on the crystallization behavior of MIL-96 were studied. HNO3 enhanced the dissolution of the α-Al2O3 monolith and the growth of MIL-96. The growth rate of MIL-96 was also influenced by the synthesis temperature; a synthesis temperature of over 453 K was required for crystallization. The CO2 adsorption capacity of the prepared MIL-96 monoliths was evaluated and found to be comparable to that of the well-grown MIL-96 powdery crystal. Furthermore, the MIL-96 monoliths demonstrated good stability as their adsorption properties were retained even after 2 months of storage under atmospheric conditions.

  • Alkaline-treatment with pore-filling agent for defect-healing of zeolite membrane

    Motomu Sakai, Hayata Hori, Masahiko Matsukata

    Microporous and Mesoporous Materials   336  2022.05  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Defects in silicalite-1 membrane is readily healed by an alkaline-treatment in aqueous solutions of NaOH and organic additives such as cetyltrimethylammonium bromide (CTAB) and tetramethylammonium bromide (TMABr). In this study, we investigated the role of organic additive in the course of alkaline-treatment. From the evaluation of weight and micropore volume of silicalite-1, it was shown that 3.6 and 3.1 molecules per unit cell of CTA+ and TMA+ entered the micropore of silicalite-1 during the treatment. CTA+ or TMA+ locating in the micropore inhibited the diffusion of NaOH into the micropore of zeolite and suppressed the dissolution from the inside of crystal. In contrast, the defect in silicalite-1 membrane was not healed by using an aqueous solution of NaOH and tetrabutylammonium bromide (TMABr), which was not able to enter the micropore of silicalite-1. We concluded that the use of organic additives, which can enter the micropore, was important for the defect-healing of siliclaite-1 membrane by the alkaline-treatment.

  • Contribution of Pore-Connectivity to Permeation Performance of Silicalite-1 Membrane; Part II, Diffusivity of C6 Hydrocarbon in Micropore.

    Motomu Sakai, Yukichi Sasaki, Takuya Kaneko, Masahiko Matsukata

    Membranes   11 ( 6 )  2021.05  [Refereed]  [International journal]

    Authorship:Lead author, Corresponding author

     View Summary

    This study investigated the permeation behaviors of n-hexane and 2-methylpentane through two-types of silicalite-1 membranes that have different pore-connectivity. The permeation mechanisms of these hydrocarbons were able to be explained by the adsorption-diffusion model. In addition, the fluxes through silicalite-1 membranes could be expressed by the modified Fick's first law. The hydrocarbon fluxes through S-1S with better pore-connectivity were ca. 3-20 times larger than those through S-1M with poor pore-connectivity. For these membranes with different pore-connectivity, the activation energy of diffusion of n-hexane was 17.5 kJ mol-1 for the membrane with better pore-connectivity and 18.0 kJ mol-1 for the membrane with poorer pore-connectivity, whereas for 2-methylpentane it was 17.9 and 33.0 kJ mol-1, respectively. We concluded that the pore-connectivity in silicalite-1 membrane significantly influences the molecular diffusivities.

  • Contribution of Pore-Connectivity to Permeation Performance of Silicalite-1 Membrane; Part I, Pore Volume and Effective Pore Size.

    Motomu Sakai, Yukichi Sasaki, Takuya Kaneko, Masahiko Matsukata

    Membranes   11 ( 6 ) 399 - 399  2021.05  [Refereed]  [International journal]

    Authorship:Lead author, Corresponding author

     View Summary

    The micropore volumes and effective pore sizes of two types of silicalite-1 membranes were compared with those of a typical silicalite-1 powder. The silicalite-1 membrane with fewer grain boundaries in the membrane layer showed similar micropore volume and effective pores size to those of the silicalite-1 powder. In contrast, when the silicalite-1 membrane contained many grain boundaries, relatively small micropore volume and effective pore size were observed, suggesting that narrowing and obstruction of the micropore would occur along grain boundaries due to the disconnection of the zeolite pore. The silicalite-1 membrane with fewer grain boundaries exhibited relatively high permeation properties for C6-C8 hydrocarbons. There was an over 50-fold difference in benzene permeance between these two types of membranes. We concluded that it is important to reduce grain boundaries and improve pore-connectivity to develop an effective preparation method for obtaining a highly permeable membrane.

  • Self-defect-healing of silicalite-1 membrane in alkaline aqueous solution with surfactant

    Motomu Sakai, Hayata Hori, Masahiko Matsukata

    MATERIALS ADVANCES    2021.05  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Alkaline treatment with surfactant was applied to silicalite-1 membrane for defect healing. By immersion of silicalite-1 membrane into an aqueous solution of sodium hydroxide and cetyltrimethylammonium bromide (CTAB), defects among crystals were sealed, with amorphous silica leached from the membrane itself. During the treatment, the zeolite pores in the membrane were protected by CTAB from excess alkaline etching. As a result, the separation performance of silicalite-1 membrane was successfully improved by this post-treatment without a decrease in permeability due to the collaborative effect of NaOH and CTAB. The separation factor for n-hexane/2,3-dimethylbutane mixture increased from 86.5 to 559 after only a 15 min treatment. In addition, the separation performances of other zeolite membranes (Na-*BEA, Na-ZSM-5, and Na-MOR) were also improved by the treatment. This novel defect-healing technique breaks the trade-off line of permeation and separation performance observed with previous post-treatments.

    Crystals   10 ( 10 ) 949 - 949  2020.10  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    © 2020 by the authors. Licensee MDPI, Basel, Switzerland. Silicalite-1 membrane was prepared on an outer surface of a tubular α-alumina support by a secondary growth method. Changes of defect amount and crystallinity during secondary growth were carefully observed. The defect-less well-crystallized silicalite-1 membrane was obtained after 7-days crystallization at 373 K. The silicalite-1 membrane became (h0l)-orientation with increasing membrane thickness, possibly because the orientation was attributable to “evolutionally selection”. The (h0l)-oriented silicalite-1 membrane showed high p-xylene separation performance for a xylene isomer mixture (o-/m-/p-xylene = 0.4/0.4/0.4 kPa). The p-xylene permeance through the membrane was 6.52 × 10−8 mol m−2 s−1 Pa−1 with separation factors αp/o, αp/m of more than 100 at 373 K. As a result of microscopic analysis, it was suggested that a very thin part in the vicinity of surface played as effective separation layer and could contribute to high permeation performance.

  • Preferential Adsorption of Propylene over Propane on a Ag-Exchanged X-Type Zeolite Membrane

    ACS applied materials & interfaces   12 ( 21 ) 24086 - 24092  2020.05  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    We investigated the adsorption properties of propylene and propane on an olefin-selective Ag-X membrane and discussed the contribution of adsorption selectivity to propylene/propane separation performance through this membrane. The isotherms of propylene and propane on Ag-X membranes were measured in unary systems at 313 K. The amount of propylene adsorbed on the Ag-X membrane at a lower pressure increased remarkably compared with that on the Na-X membrane. Such a change of adsorption property could induce excellent separation property for the Ag-X membrane. We compared the adsorption properties in a binary system calculated based on the Markham-Benton approach with the results of a permeation test. The molar fractions of propylene in the adsorbed phase in the binary system provided good agreement with propylene purity on the permeation side of the Ag-X membrane. These results clearly show that permeation selectivity of the Ag-X membrane for the propylene/propane mixture is mainly governed by adsorption selectivity.

     View Summary

    © 2019 The Authors Tubular zeolite *BEA membrane was prepared by a hydrothermal secondary growth method in the absence of an organic structure directing agent (OSDA). Membrane formation process was carefully observed by using FE-SEM, XRD, and N2 adsorption, and the role of seed crystals on the support surface was discussed. Seed crystals loaded on the outer surface of a tubular porous alumina support partially dissolved and a small amount of seeds remained in an amorphous layer formed on the support surface in the early stage of secondary growth step. Subsequently, crystal growth of remaining crystals occurred, and a continuous *BEA layer was obtained following crystallization for 7 days at 393 K. In the secondary growth step, the supported seed layer played an important role in inducing the formation of a high local concentration in the vicinity of the support surface. The prepared OSDA-free *BEA membrane was then applied in the separation of hydrocarbons. We found that this membrane contained very few defects, and exhibited a high ideal selectivity for cyclohexane/1,3,5-trimethylbenzene mixture of 100, with cyclohexane permeance of 1.0 × 10−7 mol m−2 s−1 Pa−1 based on molecular sieving effect at 623 K.

     View Summary

    © 2019 American Chemical Society. Propylene/propane and ethylene/ethane separation was examined with Ag-exchanged X-type zeolite membrane (Ag-X membrane). The Na-X membrane was prepared on a porous tubular α-alumina support by a secondary growth method. The resulting Na-X membrane was ion-exchanged by using AgNO 3 aq. Olefin selectivities in both mixtures were markedly improved after the ion exchange from Na to Ag cation. The Ag-X membrane exhibited a maximum propylene selectivity of 55.4 with a permeance of 4.13 × 10 -8 mol m -2 s -1 Pa -1 at 353 K for a propylene/propane (50:50) mixture. This membrane also exhibited a maximum ethylene selectivity of 15.9 with a permeance of 9.04 × 10 -8 mol m -2 s -1 Pa -1 at 303 K for an ethylene/ethane (50:50) mixture. We consider that the strong interaction between olefin and Ag cation plays an important role for the appearance of such high selectivity of olefin.

  • Strategy of Development on Zeolite Membrane for Forward Osmosis Operation; Effects of Structural Parameter of Support Layer and Si/Al Ratio of ZSM-5 Layer on Water Flux

    Journal of Chemical Engineering of Japan   56 ( 1 )  2023.08  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    The strategy of development on zeolite membrane for forward osmosis was investigated. Defect-less MFI membranes with almost the same thickness were successfully prepared on five kinds of a-Al(2)O(3 )tubular supports having different structural parameters. The water flux through these membranes could be expressed as a function of the structural parameter of support. Moreover, the effect of the Si/Al ratio in zeolite layer, which serves as an index of hydrophilicity, was examined. As a result, a membrane with a relatively hydrophilic character, having Si/Al ratio = 18.6, showed a higher water flux. Conversely, both water and salt hardly penetrated through a hydrophobic membrane (Si/Al = 8). Reducing the structural parameter in the support layer and improving the hydrophilicity of the active layer is crucial to achieving high water-permeability of zeolite FO membrane.

     View Summary

    Y-type zeolite membranes were prepared on a porous tubular α-alumina support by a secondary growth process. Various experimental conditions such as seed size, pH of seed solution, and degassing of support were examined for understanding their influence on the membrane deposition process. The experimental results showed that the potential of alumina support surface and the USY seed slurry plays a significant role in controlling the electrostatic interaction between seed particles and support surface and also the aggregation of USY seed particles in the slurry. In addition, we also noted the significance of the capillary forces working at the three-phase interface on the support surface and is a key factor that governs the seeding behavior onto the tubular support surface. Optimization of these parameters resulted in crack-free compact membranes that were able to effectively separate a mixture of isopropyl alcohol and water in a vapor-phase separation process.

     View Summary

    <title>Abstract</title>Isotopes of heavier gases including carbon (13C/14C), nitrogen (13N), and oxygen (18O) are highly important because they can be substituted for naturally occurring atoms without significantly perturbing the biochemical properties of the radiolabelled parent molecules. These labelled molecules are employed in clinical radiopharmaceuticals, in studies of brain disease and as imaging probes for advanced medical imaging techniques such as positron-emission tomography (PET). Established distillation-based isotope gas separation methods have a separation factor (<italic>S</italic>) below 1.05 and incur very high operating costs due to high energy consumption and long processing times, highlighting the need for new separation technologies. Here, we show a rapid and highly selective adsorption-based separation of 18O2 from 16O2 with <italic>S</italic> above 60 using nanoporous adsorbents operating near the boiling point of methane (112 K), which is accessible through cryogenic liquefied-natural-gas technology. A collective-nuclear-quantum effect difference between the ordered 18O2 and 16O2 molecular assemblies confined in subnanometer pores can explain the observed equilibrium separation and is applicable to other isotopic gases.

    Journal of Visualized Experiments   2020 ( 156 )  2020.02  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    © 2020 Journal of Visualized Experiments. Membrane separation has drawn attention as a novel-energy saving separation process. Zeolite membranes have great potential for hydrocarbon separation in petroleum and petrochemical fields because of their high thermal, chemical, and mechanical strength. A *BEA-type zeolite is an interesting membrane material because of its large pore size and wide Si/Al range. This manuscript presents a protocol for *BEA membrane preparation by a secondary growth method that does not use an organic structure-directing agent (OSDA). The preparation protocol consists of four steps: pretreatment of support, seed preparation, dip-coating, and membrane crystallization. First, the *BEA seed crystal is prepared by conventional hydrothermal synthesis using OSDA. The synthesized seed crystal is loaded on the outer surface of a 3 cm long tubular α-Al2O3 support by a dip-coating method. The loaded seed layer is prepared with the secondary growth method using a hydrothermal treatment at 393 K for 7 days without using OSDA. A *BEA membrane having very few defects is successfully obtained. The seed preparation and dip-coating steps strongly affect the membrane quality.

  • ゼオライトナノシート分離膜の開発

    2023  

     View Summary

     カーボンニュートラル社会実現に向けて、二酸化炭素や水素、アンモニア、酸素等の有効利用のため、省エネルギーなガス分離精製技術が求められている。ゼオライト膜は日本企業から実用化されており、省エネルギーかつ簡便な膜分離技術として既に利用されているが、大規模実装に向けた更なる発展・普及のためには、透過性の向上が課題である。本研究では、従来型多孔質膜の10倍以上の透過性を目標として、ナノシート化したゼオライトを集積させた超高速ガス分離膜を開発する。 本研究では、複数種類のナノシートゼオライトの合成に成功した。また、得られたナノシートゼオライトを積層するために複数(ろ過法、プレス法等)の手法を検討した。その結果、ナノシートゼオライトが積層した薄膜を得ることができ、極めて高いガス透過性を有することを見出した。 本研究の成果は、2024年度学術変革領域(A)(公募研究)への応募へとつながった。

  • 二酸化炭素資源化膜反応器のための高温水蒸気分離膜の開発

    2023  

     View Summary

     2050年カーボンニュートラルの達成のために、大規模な二酸化炭素資源化技術の研究開発は急務である。近年、二酸化炭素から化学品や燃料を製造する種々の反応(逆水性ガスシフト、メタノール合成、Fischer-Tropsch合成等)が注目されている。 これらの反応では、副生成物として生成する多量の水蒸気が、反応速度の低下や反応器および触媒の劣化を引き起こす。反応系内から分離膜を用いて副生成物である水蒸気を選択的に除去することで、反応の効率化や反応器・触媒の長寿命化が期待される。 本研究では、種々のゼオライト膜を合成し、高温水蒸気とガス(水素やCO2)混合物に対する透過分離特性を評価した。その結果、ゼオライトの骨格構造およびゼオライト中のカチオン種が高温水蒸気透過選択性に大きな影響を与えることがわかった。 本研究成果の一部は、2024年度科研費(若手)への応募へつながった。

  • 新規ゼオライト膜の合成法およびその透過分離特性の検討

    2014  

     View Summary

     本研究では、分離プロセスの省エネルギー化に資する材料として新規ゼオライト膜の開発を行った。既報に従い新規ゼオライト粉末の合成を行い、その耐酸性について試験を行った。その結果、新規ゼオライトは非常に高い耐酸性を有することが明らかとなった。次に、調製条件(結晶化温度、結晶化時間、合成液組成)を鋭意検討し、新規ゼオライトを多孔質アルミナ支持体上へ薄膜化した。得られた新規ゼオライト膜はアルコールから水を選択的に分離することが可能であった。今後は酸からの脱水やガス分離(窒素/酸素, 窒素/二酸化炭素)にも応用する予定である。
