2. State Key Laboratory of Heavy Oil， Qingdao 260000， Shandong China）Abstract：In order to improve the technical and economic feasibility of hydrocatalytic cracking of lignite and residue， a miniature simulated industrial environment was established in the laboratory， and the experimental data of hydrocatalytic cracking with lignite， residue and mixture of lignite residue oil were compared and analyzed. It is found that the hydrocracking process of lignite residue oil mixture greatly improves the process efficiency of lignite hydrocracking， and has great advantages in energy consumption，emission，etc.
