Abstract

An alkaline modified activated carbon desulfurizer is prepared from the following raw materials by weight: 100-120 parts of activated carbon, 4-5 parts of sodium hydroxide, 30-34 parts of diatomite, 3-4 parts of glass powder, 4-5 parts of silicon dioxide, 8-10 parts of modified attapulgite, and a proper amount of water. According to the invention, with the use of sodium hydroxide, the desulfurization speed is high, and the efficiency is high; diatomite is added as a carrier, which provides good adsorbing effect; with the desulfurizer of the invention, no harmful substance is generated after desulfurization, which is more environment-friendly and safer; the desulfurizer of the invention is easy to regenerate, and the preparation method of the invention is simple in process, suitable for industrial production, and cost-saving.

Description

technical field [0001] The invention relates to a modification method of non-metallic ore, in particular to an alkaline 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 co...
