Pyrolysis and catalytic cracking reaction of four kinds of coal liquefaction residues were carried out by use of a TG apparatus and a GC with pyrolyzer under inert gases. In the TG analyses, maximum weight decrease of each sample was observed at heating rate of 5℃/min and Ilinois No. 6 coal residue exhibited a little larger weight decrease than others. The catalytic cracking reaction with a FCC catalyst showed that lighter fractions of which the retention time is shorter than naphthalene increased.
