Preparation and Characterization of Super Pure Coal

Abstract:

Industrial washing oil as solvent, super pure coal was extracted and prepared from raw coal using heat extraction technology. The structures of raw coal and super pure coal were characterized by thermogravimetry and Fu Liye infrared spectrum. The results showed that the heat extraction rate of super pure coal was decreased with the increasing of coalification degree. The ash of raw coal which were silicate and alumina can be concentrated by heat extraction technology into coal residue and the mixtures of various structure were mainly composed of aromatic hydrocarbons also can be extracted effectively.
