摘要：為了提升褐煤與渣油加氫催化裂解的技術可行性和經濟可行性，在實驗室中建立微縮模擬工業(yè)環(huán)境，比較分析單純使用褐煤、單純使用渣油及使用褐煤渣油混合物進行加氫催化裂解的實驗數據。發(fā)現(xiàn)褐煤渣油混合物的加氫裂解工藝大幅度提升了褐煤加氫裂解的工藝效率，且在能耗、排放等方面具有較大優(yōu)勢。

關鍵詞：褐煤;減壓渣油;加氫催化裂解;技術可行性;環(huán)保;能耗

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.
