The invention discloses a carbonyl sulfide hydrolysis catalyst, which comprises the following components in parts by weight: 0.001-10 parts of gold chloride, 0.001-10 parts of silver nitrate, 0.1-25 parts of alkali metal compound, 0.1-25 parts of alkaline earth metal compound, 65-99 parts of catalyst and 0.01-100 parts of deionized water. The invention belongs to the technical field of catalysts for removing organic sulfur, in particular to a carbonyl sulfide hydrolysis catalyst and a preparation method thereof, which achieve the aim by adopting dual-functional active components. The catalyst is suitable for wide temperature range from low temperature (20 ℃) to medium temperature (400 ℃), the sulfur content in raw materials is not particularly limited, the catalyst can keep long-time catalytic activity in the range that the oxygen content in raw material gas is up to 5%, and the catalyst has good sulfation resistance and sulfur deposition resistance. |
