Catalyst and application, and method for removing carbonyl sulfide in natural gas

Abstract

A catalyst can be used for removing carbonyl sulfide in natural gas. The catalyst has a carrier, and an alkali metal oxide and nickel oxide which are loaded on the carrier. Based on the total weight of the catalyst, the content of the carrier is 90-97 wt %, the content of the alkali metal oxide is 2-6 wt %, and the content of the nickel oxide is 1-4 wt %. At least part of the carrier is AlO(OH), χ-Al2O3 and η-Al2O3 phases. The catalyst can achieve a COS conversion rate of greater than or equal to 99% and a service life of 8 years or above, and can effectively reduce the content of carbonyl sulfur in natural gas.
