The catalyst for carbonyl sulfide hydrolysis at moderate temperature was prepared by using γ-Al₂O₃ as a carrier and TiO₂ as the modifying agent. The atmospheric effects for carbonyl sulfur hydrolysis at moderate temperature were carried out in simulated coal gas using a fixed-bed reactor. And the crystal phases of both fresh catalysts and used catalyst were characterized by using X-ray diffraction. The experimental results show that COS stable conversion was about 80% in simulated coal gas and less than that in N₂ atmosphere. CO, CO₂ and H₂ in stimulated coal gas may decrease COS conversion due to these gases adsorption on surface activity site of catalyst. The conversion of COS has a maximum value with the change of the ratios of water vapor to COS concentration. Hydrolysis of COS is one-order reaction for COS concentration. There was no hydrogenlysis in H₂-containing atmosphere for COS hydrolysis catalyst, and there was no poisoning for COS hydrolysis catalyst in simulated coal gas atmosphere.
