摘要
Abstract
Pyrolysis of two typical Chinese coal liquefaction residues (Shenhua and Shengli) and their solvent extracts was carried out by TG. The results show that Shenhua and Shengli residue contain similar content of light component, and their weight losses in TGA are similar. However, the different composition of light component in the two residues leads to their difference in TG curves. As increasing of heating rate, the maximum weight loss rate and its corresponding temperature increase. The calculated weight loss calculated from the constitutes is approximately the actual value of the residue. From the kinetic analysis, it is found that the weight loss calculated by the experimental E and k0 agree well with that obtained from the experiment. The weight loss is mainly caused by evaporation of volatile matter which can be extracted by solvent.关键词
