Application of FC-16B catalyst in hydrocracking unit

The main technical features and process flow of a hydrocracking unit in Daqing Petrochemical Company are introduced. The main process of device start-up is discussed, including catalyst loading, catalyst desiccation, catalyst sulfuration, catalyst passiva- tion and feedstock switching. The main operating parameters and processing capacity, feedstock and products properties, material bal- ancing and product yield, energy consumption and equipments running situation are studied by performance testing and the calibration data are also comprehensively analyzed. The operation and performance tests show that the unit worked steadily and the performance of FC-16B catalyst is good, which has advantages of wider adaptability to different sources of feedstock, flexible in production option, ex- cellent product quality and rational distribution, high liquid yield and low processing loss, far lower energy consumption than design in- dex.
