Abstract

A modified activated carbon adsorbent for low concentration organic exhaust gases is prepared from the following raw materials: by weight, 100-120 parts of activated carbon, 2-3 parts of cerium oxide, 1-2 parts of ammonium persulfate, 70-80 parts of diatomite, 3-4 parts of lignin, 8-10 parts of modified attapulgite and a moderate amount of water. The modified activated carbon adsorbent uses the cerium oxide, the ammonium persulfate and other oxidants for quickly decomposing organic matters, and also uses the diatomite for effective adsorption of dust particles; the modified activated carbon adsorbent is obtained by spray drying, the obtained modified activated carbon adsorbent particles are tiny, fluffy, large in interspace and good in adsorption effect, and the modified activated carbon adsorbent is suitable for purification of the low concentration organic exhaust gases, simple in process and suitable for industrial production.

Description

technical field [0001] The invention relates to a modification method of non-metallic ore, in particular to a modified activated carbon adsorbent for low-concentration organic waste gas 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 ...
