Abstract

The invention relates to a modified activated carbon hydrogen sulfide adsorbent which is prepared from the following raw materials in parts by weight: 100-120 parts of activated carbon, 12-14 parts of copper sulfate, 20-23 parts of high-alumina bauxite, 4-5 parts of magnesium oxide, 5-6 parts of calcium oxide, 6-8 parts of sodium carbonate, 8-10 parts of modified attapulgite and a right amount of water. According to the invention, the activated carbon is modified by using copper sulfate, high-alumina bauxite, magnesium oxide, calcium oxide and sodium carbonate, so that the removal efficiency of hydrogen sulfide is increased; the reaction activity of the activated carbon is improved by processes such as calcination and spray drying, thereby being favorable to the removal of sulfides contained in low-concentration fume. The modified activated carbon hydrogen sulfide adsorbent is simple in process and easily available in raw materials, and can realize industrial production.

Description

technical field [0001] The invention relates to a method for modifying non-metallic ore, in particular to a modified activated carbon hydrogen sulfide adsorbent 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 ...
