Preparation of Activated Carbon from Coke Powder by KOH Activation

Abstract:

With the enhancement of environmental awareness and the development of coking technology, large domestic coking plant With the enhancement of environmental awareness and the development of coking technology, large domestic coking plant With the enhancement of environmental awareness and the development of coking technology, large domestic coking plant will use CDQ technology to deal with Coke. So a great number of coke powder will be produced in coking enterprises every day. This paper use coke power, the waste of coking enterprises, as raw material to produce activated carbon with good adsorption property by chemical activation. The surface chemical composition and surface area of the activated carbon were investigated. The effects of activation conditions on the characteristics of the activation carbons were studied.As a result, activated carbon with an iodine adsorption capacity of 1020mg/g, a methylene blue adsorption capacity of 365 mg/g and a specific surface area of 1600 m2/g was obtained. These adsorption capacities were almost the same as ordinary activated carbon on the market.
