摘要: Water-gas shift (WGS) reaction is an important intermediate step in converting fossil fuels to hydrogen (H2) for chemical production or power generation. Catalytic membrane reactor with a H2 perm-selective can improve WGS conversion and separate from carbon dioxide (CO2) simulta- neously. In this work, experimental work modeling analysis were performed on tubular ZSM-5/silicalite bilayer composed of 3 lm ZSM-5 layer, 8 silicalite base layer 2 YSZ barrier supported a-alumina substrate. The studies demonstrated that temperature, H2O/CO ratio, gas hourly space velocity (GHSV) feed pressure are key factors determine the performance zeolite reactor.
