F-T合成加氢裂化催化剂的工业应用

F-T合成油低温工艺产物中有大于质量分数40%的石蜡生成,必须对其进行加氢裂化生产优质的中间馏分油。加氢裂化关键在于高性能催化剂的研究开发，概述了近年来加氢裂化催化剂在国内外的应用现状。FC-14及SC-I催化剂在内蒙古伊泰煤制油有限责任公司的运行结果表明，SC-I催化剂表现出良好的活性及较高的中间馏分油选择性，在总进料20 t·h^-1、反应器入口氢分压7.0 MPa、氢油体积比800和总体积空速（2.0~15.0） h^-1条件下，反应器出口温度约340 ℃，总温升14 ℃，表现出较高的反应活性及灵活的温度调控性，柴油收率上升约3~4个百分点，具有较高的中油选择性。

Commercial application of hydrocracking catalysts for Fiseher-Tropsch synthesis

F-T synthetic oil is mainly composed of n-paraffins of alkanes and alkenes,in which wax is accounted for 40%. The production maximization of the high quality middle distillates are one of the effec-tive ways to make full use of F-T synthetic wax. The development and application of the catalysts with high performance is the key of hydrocracking technology. The recent research progress in hydrocracking cata-lysts and their application status at home and abroad were reviewed. The commercial applications of FC-14 and SC-I catalysts in Inner Mongolia Yitai CTO Co. ,Ltd. were especially introduced. The running results showed that SC-I catalyst exhibited good activity and selectivity to middle distillate. Under the condition of total feedstock rate 20 t·h-1,hydrogen partial pressure of reactor inlet 7. 0 MPa,hydrogen/oil volume ratio 800 ,total volume airspeed（ 2 . 0-15 . 0 ）h-1 ,reactor outlet temperature about 340 ℃ and overall temperature rise 14 ℃,the catalyst exhibited high reaction activity,flexible temperature control perform-ance and high selectivity to medium oil,and diesel yield increased about 3 -4 percentage point at the same time.
