Metal oxide desulfurizer as well as preparation method and application thereof

The invention provides a metal oxide desulfurizing agent as well as a preparation method and application thereof, and belongs to the technical field of gas purification and desulfurization. The metal oxide desulfurizer is obtained by dipping a nickel oxide or molybdenum oxide precursor on activated carbon, drying and roasting, and the metal oxide desulfurizer comprises an oxygen-containing functional group and a metal oxide on the surface of the activated carbon. The metal oxide desulfurizer is used for removing sulfurized substances to generate metal sulfide, and the metal sulfide is used as a hydrogenation catalyst of thiophene sulfur. 本发明提供了一种金属氧化物脱硫剂及其制备方法和应用，属于气体净化脱硫技术领域。所述金属氧化物脱硫剂通过将氧化镍或氧化钼前驱体浸渍到活性炭上经过干燥和焙烧获得，所述金属氧化物脱硫剂包括活性炭表面上的含氧官能团和金属氧化物。所述金属氧化物脱硫剂在脱除硫化和物后产生的金属硫化物，作为噻吩类硫的加氢催化剂。
