Activated carbon adsorbent for adsorbing gasoline vapor

Abstract

The invention discloses an activated carbon adsorbent for adsorbing gasoline vapor. The activated carbon adsorbent is characterized by being prepared from the following raw materials in parts by weight: 100-150 parts of sludge, 13-17 parts of maize straw, 15-24 parts of peanut shell, 10-15 parts of manganese ore flour, 30-50 parts of zinc chloride, 13-16 parts of magnesium silicate, 5-8 parts of silicon dioxide, 3-5 parts of polyvinyl alcohol, 3-5 parts of polyacrylamide, 6-8 parts of basalt fiber, 2-4 parts of polyisobutylene succinimide, 8-11 parts of magnesium oxide and proper amount of distilled water. By adding the basalt fiber, the polyisobutylene succinimide and the magnesium oxide, the strength and the adsorption capacity of the sludge activated carbon can be enhanced, and the adsorbent has good purification and cleaning effects on gasoline; and the adsorbent prepared by the invention is high in gasoline adsorption capacity, good in desorption, high in strength, capable of effectively relieving the harm to environment and human bodies and is worthy of popularizing.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an activated carbon adsorbent for adsorbing gasoline vapor and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, the increase of urban population and the strengthening of environmental protection awareness, the discharge of urban industrial wastewater and domestic sewage is increasing, the rate of urban sewage treatment is also increasing year by year, and the sludge generation rate of sewage plants is also increasing sharply. The sludge of the sewage treatment plant has a high water content, a large amount of organic matter, toxic and harmful substances, and semi-dry solid waste with complex rheology. It has a large capacity, is easily corrupted, unstable, and has a bad smell. cause serious environmental pollution. Activated carbon is a porous adsorption material with rich pore structure, high specific surface area and strong adsorp...

Problems solved by technology

At present, there are mainly chemical, biological, and photocatalyst products on the market. These products are expensive and have certain restrictions on use conditions. Activated carbon has the advantages of affordable price, convenient use, no pollution, no side effects, and ideal use effects. However, Ordinary activated carbon adsorbents are easy to be saturated, easy to fall powder and scattered, the use time is not long, and the separation is not easy, and the adsorption efficiency is low.
