Abstract

The invention discloses a method for preparing a fine desulfurizer with water quenching slag of nickel concentrates, which is characterized by using the water quenching slag of nickel concentrates as the raw material for preparing the fine desulfurizer, using acid to treat the water quenching slag and then adding alkali for neutralization under the condition of introducing air and stirring, mixing the obtained precipitates and binders evenly and preparing the fine desulfurizer by extrusion molding after kneading by adding water. The water quenching slag contains the compounds of Ni, Cu, Zn, Fe and Cr. The method makes good use of the industrial and metallurgical wastes harmful to the environment. The prepared fine desulfurizer has less than 0.1*10-6(v / v) degree of purification toward the feed gases, stable desulfurization effect and low cost, realizes energy conservation and emission reduction, changes wastes into valuables and has obvious economic and social benefits.

Description

technical field

[0001] The invention belongs to the recovery and reuse of industrial waste, and relates to a method for preparing a fine desulfurizer by utilizing the water-quenched slag of a nickel smelter. technical background

[0002] Sulfur is the main poison that causes catalyst poisoning, and most high-efficiency catalysts need desulfurization treatment to prolong the service life of the catalyst. h 2 S is the main poison that causes catalyst poisoning, and it widely exists in various chemical raw material gases. Therefore, it is very necessary to desulfurize the raw material gas, and the key is to reduce the desulfurization cost and improve the desulfurization efficiency.

[0003] In recent years, nearly 1.2 billion tons of industrial wastes have been produced in my country every year. Among the industrial wastes, more than 40 million tons of fly ash have not been utilized every year; the accumulated tailings of various metal mines have reached 4 billion tons, and mo...
