Abstract

The invention discloses active carbon prepared from wastes. The active carbon is prepared from the following raw materials in parts by weight: 10 to 15 parts of waste ceramic sheets, 10 to 15 parts of waste tire rubber, 6 to 10 parts of coal slag, 10 to 16 parts of 1,4-cyclohexanedimethanol, 3 to 6 parts of 2-naphthol-6,8-dipotassium disulfonate, 7 to 10 parts of ethopabate, 6 to 12 parts of isoamyl salicylate, 3 to 7 parts of dimethicone, 10 to 15 parts of mercaptosuccinic acid and 8 to 12 parts of resorcinol diglycidyl ether. The waste ceramic sheets, the waste tire rubber and the coal slag are used as raw materials to be prepared into active carbon with high mechanical strength, good adsorption performance and long service life by virtue of steps such as immersing, carbonization and the like, so that the cost is saved, and the resource utilization rate is increased.

Description

technical field [0001] The invention belongs to the field of activated carbon preparation, in particular to an activated carbon prepared from waste and a method thereof. Background technique [0002] Activated carbon is a black powder or block, granular, honeycomb amorphous carbon or regular crystalline carbon. In the early days, it was mainly prepared from wood, hard nut shells or animal bones through carbonization and activation; after that, people pulverized and shaped coal or used uniform coal particles to carbonize and activate to obtain activated carbon. Its composition is mainly carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. Because of its porous carbon, low bulk density and large specific surface area, it is widely used in petrochemical, electric power, chemical, food, gold, environmental protection and other industries. Especially because of its good catalytic performance and adsorption performance, it has b...
