Abstract
The invention provides a Co-based catalyst for production of sulfur through reduction of SO2 in flue gas as well as a preparation method and an application of the Co-based catalyst. The catalyst comprises a supporter as well as an active component and an aid which are applied to the supporter, wherein the active component is oxide of Co, and the aid is one or at least two of oxides of Cu, Ni, La, Mg, Ca or Ba. The preparation method comprises the steps as follows: the active component and the aid are supported on the supporter with an equivalent-volume impregnation method, drying, roasting and vulcanization are performed, and the Co-based catalyst is prepared. The Co-based catalyst contains uniformly dispersed component, stable performance and uniform particle size and is applicable to catalysis of SO2 in the flue gas to produce sulfur in a fixed bed reactor.
