Activated carbon and production thereof

摘要

A preparing process of activated carbon includes steps of: combusting scrap tires containing metal wire at 400 DEG C. to 900 DEG C. under the presence of oxygen, carbon dioxide and vapor; reheating the generated combustible gases up to 800 DEG C. to 900 DEG C. by adding a further fuel; causing the exhaust gas to heat-exchange with a water pipe boiler so that the temperature of the exhaust gas downs to 180 DEG C. to 250 DEG C.; and introducing the exhaust having a temperature of 180 DEG C. to 250 DEG C. into an electric dust collector so as to collect activated carbon. The particle size of the thus obtained distributed substantially in a range of 90 to 110 mesh and the CEC (cation exchange capacity) of the activated carbon falls within 30 to 40.
