摘　　要：为了拓宽加氢裂化装置的原料来源,中国石化齐鲁分公司1 400 kt／a加氢裂化装置在加强对原料的过滤,提高加氢精制深度,充分利用高抗氮裂化催化剂性能等现有条件的情况下,进行了提高掺炼焦化蜡油比例的工业试验,掺炼率最大可至25％。当掺炼率为20％时,精制反应器床层的总温升比单炼VGO时上升了20℃,平均反应温度实际上升了6.1℃,氢耗从202.8 m3／t上升到236.5 m3／t。掺炼焦化蜡油后对装置的平稳操作和产品质量、产品分布无不良影响。The commercial test for increasing the blending ratio of coker gatch in VGO feedstock was carried on the 1. 4Mt/a hydrocracking unit of Qilu Petrochemical Company for widening the feedstock source. The adopted measures included enhancing the feedstock filtration, deepening the hydrorefining and using the nitrogen tolerance catalyst. The highest blending ratio of coker gatch could reach 25%. At a coker-gatch blending ratio from 0 to 20% , the overall temperature rise of the refining reactor raised 20℃ , the catalyst average temperature raised 6. 1℃, and the hydrogen consumption increased from 202. 8m3/t to 236. 5m3/t. No harmful effect was observed on stable operation, product slate and product quality.
