Abstract

The invention discloses a difunctional hydroxyl iron oxide desulphurization agent and a preparation method thereof. The method adopts ferrite and sodium metaaluminate as raw materials to have homogenous co-precipitation reaction, the one-step synthesis is performed in a co-precipitation method, impurities are removed in a separation manner, then by virtue of a series of steps such as half drying,addition of adhesive, mixing pre-extrusion, extrusion molding and drying, the difunctional hydroxyl iron oxide desulphurization agent is finally obtained. By adopting the desulphurization agent, the hydrogen sulfide and carbonyl sulfide can be removed, and the desulphurization agent is excellent in performance under the saturated sulfur capacity and regeneration test. The preparation method is simple in preparation process, stable in product, capable of simplifying the procedures, and capable of effectively reducing the equipment investment, so that the difunctional hydroxyl iron oxide desulphurization agent is good in industrial application potential.

Description

technical field

[0001] The invention discloses a bifunctional iron oxyhydroxide desulfurizer and a preparation method thereof, belonging to the field of gas purification and desulfurizer preparation techniques. Background technique

[0002] During the production process of coal chemical industry and petrochemical industry, sulfur-containing raw material gas that seriously pollutes the environment will be produced. How to effectively remove sulfide in gas has become an important topic in the research of coal chemical industry and petrochemical industry at the present stage. The existing forms of sulfide in raw gas include inorganic sulfur and organic sulfur. Inorganic sulfur includes hydrogen sulfide and sulfur dioxide. Organic sulfur includes mercaptan, carbonyl sulfide, thiophene, etc. The removal of organic sulfur usually needs to be divided into physical absorption or chemical absorption. The chemical method is to hydrolyze or hydrogenate organic sulfur into inorganic su...
