Abstract

The invention belongs to the technical field of desulfurizing agent preparation, and particularly relates to a deep purification fine desulfurizing agent and a preparation method thereof, wherein thedesulfurizing agent comprises at least one selected from germanium, tin, bismuth and antimony or oxides thereof, aluminum oxide, nanometer zinc oxide, a transition metal oxide, an alkali metal or alkaline earth metal compound, and a lanthanum-based metal or an oxide thereof, and can remove organic sulfur and inorganic sulfur from synthesis gas at a temperature of 40 DEG C under a space velocity of16000 h<-1> to reduce the total amount of the organic sulfur and the inorganic sulfur in the synthesis gas to 3 ppb from 20 ppm, such that the desulfurizing agent has characteristics of good desulfurizing effect and high activity. According to the present invention, the method has characteristics of simple process, short preparation period, low energy consumption, and easy operation and implementin actual production; and the desulfurizing agent prepared by the method can remove organic sulfur and inorganic sulfur at the same time.

Description

technical field [0001] The invention belongs to the technical field of desulfurization agent preparation, and in particular relates to a deep purification fine desulfurization agent and a preparation method thereof. Background technique [0002] The technology of clean conversion and efficient utilization of coal resources is an important energy utilization technology for my country's economic and social sustainable development and environmental friendliness. Among them, the coal gasification process is one of the clean coal technologies with the highest coal conversion efficiency. After gasification, the use of gas turbines to generate electricity is a coal One of the important ways of clean and efficient utilization. In addition to conventional H in the gas 2 , N 2 , CO, CO 2 In addition to other components, it also contains sulfides. The existence of sulfides will corrode equipment and pipelines, lead to catalyst poisoning in subsequent conversion, reforming, and synthe...
