摘要
In this study, a combined test of the WGS (water gas shift) reactor and a Pd-based composite membrane was carried out for pre-combustion CO2 capture in a coal gasifier. The two series of WGS reactions, i.e., a high-temperature shift and a low-temperature shift, were performed under a gas composition of 60% CO and 40% H-2 at 2100 kPa to imitate coal gasification. The CO2 enrichment and H-2 recovery tests at 673 K and 2100 kPa with the high-pressure membrane module after the WGS reaction presented the enriched CO2 concentration and H-2 recovery ratios of similar to 92% and similar to 96%, respectively. The long-term stability test showed that the CO2 concentration decreased to 78.2%, and CO was generated and reached to 8.8% in the retentate stream after 47 h because of reverse WGS and CO2 hydrogenation reaction on 316L stainless steel module. The stability test for similar to 3137 h showed that these catalytic activities could be successfully prevented using steel with higher Cr and Ni contents, such as 310S. The WGS-membrane combination test using the outlet gas from a real coal gasifier was continued for similar to 100 h and showed that the WGS catalysts and membrane module made of 310S would be stable under real conditions.
