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.
