新型重油催化裂化催化剂HSC的工业应用

介绍了新型重油催化裂化催化剂HSC在A炼厂140万吨/年重油催化装置上的工业标定试验及工业应用情况。工业标定试验结果表明: 与基础剂相比，干气产率和油浆产率下降, 总液收增加了1.34个百分点，汽油产率增加了5.05个百分点，液化气产率增加了1.43个百分点。产品性质没有明显变化，催化剂抗磨损强度较高。通过中间标定、总结标定及后续的长期工业应用日常统计数据结果表明催化剂HSC具有较强的重油转化能力、较高的汽油产率、较好的产物分布和产品选择性。

Commercial Application of Novel Heavy Oil Catalytic Cracking Catalyst HSC

The commercial application of a novel RFCC catalyst HSC used in an 1.4 Mt/a RFCC unit at a refinery A was introduced. The application results show that in comparison with the base catalyst, the yield of dry gas and slurry was reduced, while the total liquid yield, gasoline yield and LPG yield increased by 1.34, 5.05 and 1.43 percentage points,respectively. The properties of the products showed no significant change while the anti-abrasion strength of the catalyst was relatively high. Based on the mid-term calibration test, the summary calibration test and the daily statistics of long term industrial application practice, the HSC catalyst features a strong conversion ability of heavy oil, a high gasoline yield, a satisfactory product distribution and a good selectivity.
