Abstract

The invention discloses a processing method of a Ce-Co binary desulfurizing agent. The processing method comprises the following steps: S1, weighing a certain amount of Ce(NO3) 3.6H2O and Co(NO3)2.6H2O, and dissolving the Ce(NO3)3.6H2O and the Co(NO3)2.6H2O in deionized water; S2, carrying out violent stirring, and carrying out the next step of operation after stirring is completed; S3, putting alumina pellets into the solution; S4, performing suction filtration on the pellets, and washing the pellets with deionized water and absolute ethyl alcohol in sequence; S5, conducting drying in a drying oven; and S6, heating the prepared sample in a muffle furnace, and naturally cooling the sample for later use. The Ce-Co binary desulfurizing agent is scientific and reasonable in structure and safeand convenient to use, Co and Ce in the Co-Ce composite metal oxide have a good synergistic effect, more active oxides exist on the surface of the desulfurizing agent, and the desulfurizing agent isparticularly suitable for catalytic oxidation reaction, high in removal efficiency, long in service life, capable of achieving tail end desulfurization work without consuming a large amount of electric power and suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of processing binary desulfurizers, in particular to a processing method for Ce-Co binary desulfurizers. Background technique [0002] There are many classification methods for transition metal composite oxides. According to the crystal structure, they can be divided into perovskite type, pyrochlore type, spinel type, fluorite type, scheelite type and rock salt type, etc.; according to the composition The stoichiometric ratio of metal elements to non-metal elements can be divided into integral ratio and non-integer ratio composite oxides; according to different chemical compositions, it can be divided into pre-transition element composite oxides, rare earth composite oxides, and iron-based composite oxides. things, etc.; [0003] However, the current processing method of Ce-Co binary desulfurizer has low extraction effect on Ce-Co, resulting in low removal efficiency and short service life, which consumes a...
