In C1 chemistry, an efficient route of utilizing natural gas as chemical source, natural gas is reacted with air (oxygen) and/or steam to give syngas. Hydrocarbon mixtures and a wide variety of oxygenates can be produced at temperatures of 150-300oC. Since product yield is thermodynamically limited in a large number of reactions in C1 chemistry, it would be noteworthy to consider development of membrane reactor for improving process efficacy. in-situ water separation would contribute to improving one pass-yield of a variety of reactions like methanol synthesis. We have recently developed ZSM-5 type and mordenite-type zeolite membranes for high temperature water separation from syngas. In this report, perspectives of these hydrophilic zeolite membarnes for removing water from such reaction systems will be discussed. Extended Abstract Status: Not Uploaded | ||
