Abstract

The invention discloses gasoline-containing activated carbon for exhaust gas adsorption. The gasoline-containing activated carbon comprises a carbonized material and an impregnating solution impregnated inside the carbonized material, wherein the impregnating solution comprises the following components: phosphoric acid, magnesium oxide, zinc chloride, polystyrene microspheres, gypsum powder, silica, magnesium silicate, polyacrylamide and polyisobutylene succinimide. In the invention, the impregnation solution with an adsorption effect on gasoline vapor is impregnated into the carbonized material to form the gasoline-containing activated carbon for exhaust gas adsorption with a gasoline vapor adsorption amount higher than that of the conventional common activated carbon.

Description

technical field [0001] The invention relates to an activated carbon, in particular to an activated carbon for exhaust gas adsorption containing gasoline. Background technique [0002] With the acceleration of urbanization and the increase of urban population, the number of vehicles has risen sharply, and the environmental pollution caused by automobiles has become the first source of urban air pollution. The pollution caused by automobiles to the atmosphere mainly comes from the evaporation of automobile exhaust and fuel gas. 70%, fuel vapor pollution accounted for 30%. [0003] At present, activated carbon is commonly used as an adsorbent for gasoline vapor; activated carbon is a porous carbon-containing substance, and its highly developed pore structure makes it have a large surface area, so it is easy to fully contact with toxic and harmful gases in the air. The highly developed pore structure constitutes a strong adsorption force field, endowing activated carbon with un...
