Commercial scale-up test of FC-28 hydrocracking catalyst for middle distillates production in single stage

FC-28 hydrocracking catalyst for production of middle distillates in single stage was prepared by impregnation method,using a modified Y zeolite the acidic component and W,Ni as the hydrogenation active components.The test results for the commercially scaled-up catalyst showed that its preparation technique was well-proven with good repeatability;catalytic properties of the catalyst attained those of laboratory-prepared catalyst. Test of the catalyst under different process condition showed that the catalyst had good adaptability to process condition fluctuation,appropriate activity,higher yield of middle distillates and good stability.
