Medium-and low-temperature catalytic hydrolysis of carbonyl sulfide

The hydrolysis catalysts for removing carbonyl sulfide(COS), as well as the reaction kinetics and mechanism, were reviewed.It was indicated that introducing poison-tolerant promoters,combining hydramine with hydrolysis and adopting layered double hydroxides(LDHs) for simultaneously removing H_2S and COS would be the focus on developments of COS hydrolysis catalysts.
