Abstract

The invention discloses a desulfurizing agent for removing hydrogen sulfide and carbonyl sulfide at the same time. The desulfurizing agent is prepared through the following steps that S1, a compound containing zinc, a binder and an accelerant are mixed, kneaded and formed; S2, a mixture formed after mixing, kneading and forming in the S1 is dried, and then a dried desulfurizing carrier precursor is obtained; S3, the desulfurizing carrier precursor obtained in the S2 is calcinated, and then a desulfurizing agent carrier is obtained; S4, the desulfurizing agent carrier is impregnated in a first copper salt solution, and copper active components are loaded on the desulfurizing agent carrier, wherein the first copper salt solution is an ammonium hydroxide solution of basic cupric carbonate; S5, an impregnated sample obtained in the S4 is dried and calcinated, and then the desulfurizing agent for removing hydrogen sulfide and carbonyl sulfide at the same time is obtained. The obtained desulfurizing agent is high in strength and not prone to pulverization, the impregnation effect of the active components is better, and hydrogen sulfide and carbonyl sulfide impurities in a high-temperature industrial gas source can be efficiently removed at the same time.

Description

technical field [0001] The invention relates to a preparation method of a desulfurization agent, in particular to a preparation method of a desulfurization agent for simultaneously removing hydrogen sulfide and carbonyl sulfide, and belongs to the technical field of industrial desulfurization. technical background [0002] In coke oven gas, water gas, natural gas and liquefied petroleum gas produced in coal chemical and petrochemical industries, there are a large number of sulfide impurities, which will not only cause environmental pollution, corrode metal pipes and equipment, but also cause downstream catalysts to shorten due to poisoning life. The sulfides in industrial gas sources are mainly organic sulfur such as H2S and carbonyl sulfide. Among them, carbonyl sulfide is a linear molecule with a compact molecular structure, which is approximately an ellipsoid with one big end and a small end. The physical and chemical properties are relatively special and stable, and it i...
