Abstract

A dolomite modified activated carbon desulfurization agent is prepared from the following raw materials: by weight, 100-120 parts of activated carbon, 20-23 parts of dolomite, 10-12 parts of montmorillonite, 3-4 parts of citric acid, 4-5 parts of polyacrylonitrile microsphere, 8-10 parts of modified attapulgite and a proper amount of water. The dolomite modified activated carbon desulfurization agent uses the dolomite and the montmorillonite, is dried by calcining and spraying, and has good adsorption and desulfurization performances; by addition of the polyacrylonitrile microsphere, the dolomite modified activated carbon desulfurization agent has an increased strength and is not easy to collapse; and the dolomite modified activated carbon desulfurization agent has the advantages of easily obtained raw materials, simple process and low cost, is suitable for industrial production, may not produce harmful materials, and has a good application prospect.

Description

technical field [0001] The invention relates to a modification method of non-metallic ore, in particular to a dolomite modified activated carbon desulfurizer and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on the filter screen of air con...
