The utilization of coal liquefaction residue (CLR) in 1t/d PSU was investigated. Hydrogenolysis reactions of CLR deashed by using CH_3COOH, H_2SO_4 or HF were carried out at 400℃ for 60min. The pretreatment using CH_3COOH or H_2SO_4 was effective to increase oil yield, but that using HF solution of lower concentration did not affect the increase and decrease of each fraction yield. Furthermore the activation of original catalyst in CLR was also discussed.
