Technical progress of sulfidation-resistance catalyst for CO shift
The key of the CO shift process is applying sulfidation resistance shift catalyst, so that the feed gas with sulfide can be shifted directly without removing sulfide. BASF, UCI and Topse Company have been researching and selling the Co Mo sulfidation resistance shift catalyst. The developing trend of sulfidation resistance shift catalyst is adding new catalytic promoter to improve the sulfidation resistance, toxicant resistance and oxidant resistance; improving the preparation technology of catalyst to reduce the production costs of catalyst. The action of Mo, K 2 CO 3 and TiO 2 to the catalyst is described. \[
