Expanded perlite modified activated carbon automobile exhaust desulfurizing agent, and preparation method thereof

Abstract

The invention discloses an expanded perlite modified activated carbon automobile exhaust desulfurizing agent which is prepared from the following raw materials in parts by weight: 100-120 parts of activated carbon, 5-7 parts of tricalcium aluminate, 4-6 parts of tetra calcium aluminoferrite, 8-10 parts of dolomite clay, 7-9 parts of montmorillonite, 15-20 parts of expanded perlite, 12-16 parts of calcium hydroxide, 15-20 parts of wood fiber, 4-5 parts of modified diatomite and a suitable amount of water. According to the expanded perlite modified activated carbon automobile exhaust desulfurizing agent disclosed by the invention, the expanded perlite is used for modifying the activated carbon to form loose porous powder, so high adsorption speed and larger adsorption amount are realized; quick and efficient desulfuration as well as longer effect can be realized by using tricalcium aluminate, tetra calcium aluminoferrite, dolomite clay, montmorillonite clay and calcium hydroxide as a desulfurizing agent. The expanded perlite modified activated carbon automobile exhaust desulfurizing agent disclosed by the invention has the advantages of low cost, simple technique, less environmental pollution, high desulfuration speed, easiness for regeneration, and suitability for high-concentration desulfuration of automobile exhaust and the like.

Description

technical field

[0001] The invention relates to the field of modified functional materials, in particular to an expanded perlite modified activated carbon automobile exhaust 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...
