| The active carbon is made from the high quality coal or the fruit crusts as the food materials through processing, compacting, charring, and activation. In fact, it is a kind of porous carbon material. There exist certain mechanical strength, much large specific surface areas, and strong adsorbing properties for the active carbon. It has the abilities of decolourization, deodorization, sulfur removal, debenzylation, and adsorbing in some catalyst to accelerate the chemical reactions. It is the excellent carriers of catalyst. Therefor, it is widely utilized in many fields, such as national defense, chemical engineering, petroleum, spinning and weaving, food, medicine, atomic energy, municipal construction, environmental protection, and in every aspects of the human beings' life.
