1. Deactivation of ZSM-5 zeolite during catalytic steam cracking ofn-hexane

    Fuel Processing Technology 126:343 (2014)

    H-ZSM-5 catalyst was initially active for the steam cracking of n-hexane to produce propylene and ethylene; however, the H-ZSM-5 catalyst deactivated. Understanding the deactivation reason of the ZSM-5 catalyst during the catalytic steam cracking is essential to develop the durable cat...

  5. Preparation of plate-like mesoporous material from layered silicate RUB-15.

    Journal of Nanoscience and Nanotechnology 13(4):2864 (2013) PMID 23763172

    A plate-like mesoporous material was formed from the lamellar structure of layered silicate RUB-15. RUB-15 was synthesized by a hydrothermal method, as reported previously. TMA (tetramethylammonium) ions exist in the interlayer of RUB-15 were exchanged with C16 TMA (hexadecyl-trimethyl-ammonium)...

  10. An enzyme-encapsulated microreactor for efficient theanine synthesis.

    Chemical Communications 48(56):7058 (2012) PMID 22674037

    A flow-type microreactor containing glutaminase-mesoporous silica composites with 10.6 nm pore diameter (TMPS10.6) was developed for the continuous synthesis of theanine, a unique amino acid. High enzymatic activity was exhibited by the local control of the reaction temperature.
