Embodiment Construction

[0010] A modified activated carbon adsorption desulfurizer, made of the following raw materials in parts by weight (kg): coconut shell activated carbon 110, ammonium persulfate 1, copper oxide 1, lanthanum oxide 1, chromium oxide 1, corn cob 13, agar 1, Glycerin 4, modified attapulgite 9, appropriate amount of water;

[0011] The modified attapulgite is made of the following raw materials in parts by weight (kg): attapulgite 110, jade powder 3, kaolin 9, crosslinking agent TAC 1.5, aluminum hydroxide 9, zinc stearate 2, borax 1 , titanium sulfate 16, urotropine 2, lanthanum oxide 1, chromium oxide 3, morpholine 1, and an appropriate amount of water; the preparation method is to send attapulgite, jade powder, and kaolin into a calciner, and calcined at 880°C for 2 hour, take it out, sprinkle with cross-linking agent TAC, then put it into appropriate amount of water for grinding, adjust the pH value of the grinding liquid to 4, grind for 1.5 hours to obtain a 120-mesh slurry, th...

Abstract

A modified activated carbon adsorption desulfurization agent is prepared from the following raw materials: by weight, 100-120 parts of coconut shell activated carbon, 1-2 parts of ammonium persulfate, 1-2 parts of copper oxide, 1-2 parts of lanthanum oxide, 1-2 parts of chromium oxide, 12-14 parts of corn cob, 1-2 parts of agar, 4-5 parts of glycerin, 8-10 parts of modified attapulgite and a proper amount of water. The modified activated carbon adsorption desulfurization agent containing lanthanum, chromium, copper and multiple metal oxides can more thoroughly and rapidly oxidize sulfides; the modified activated carbon adsorption desulfurization agent processed by spray drying has higher activity and stronger adsorption ability; and due to the addition of the corn cob, the modified activated carbon adsorption desulfurization agent has more spaces and can absorb more sulfides.

Description

technical field [0001] The invention relates to a modification method of non-metallic ore, in particular to a modified activated carbon adsorption 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 c...
