摘　　要：以焦化干气为原料,采用中国石化抚顺石油化工研究院开发的LH-10D焦化干气加氢专用催化剂,在反应温度为240~300℃、反应压力为3.5~7.0 MPa、气体体积空速为600~1 300h^(-1)的条件下,进行了焦化干气加氢制备乙烯原料的实验研究。加氢后焦化干气反应产物中烯烃质量分数不大于1.0%;氧质量浓度不大于1.0mg/m^3;1 800h的稳定性实验结果表明该催化剂具有良好的活性稳定性。The coker dry gas hydrofining process and appropriative catalyst LH-10D, developed by FRIPP,to prepare the feedstock for ethylene production was introduced. The optimized technical condi- tions are：a temperature of 240-300 ℃ ,a pressure of 3.5-7.0 MPa,a GHSV of 600-1 300 h^-1. Under the conditions,the olefin content of the product is less than 1.0% and oxygen content is less than 1.0 mg/m^3. The 1 800 h long-running test proves a good activity and stability of the catalyst.
