Abstract: Semi-regeneration catalytic reforming catalyst SR-1000 developed by SINOPEC Research Institute of Petroleum P rocessing was applied in a 450 kt/a reforming unit of Refinery and Chemical Industry Corporation of Yumen Oilfield Company of PetroChina. The operation results of nearly 400 days showed that the octane number RON of C5+ stabilized gasoline is 94.0 and the yield was 89.2% at a WABT of 468℃, which indicates that SR-1000 catalyst has better activity and selectivity. Under the condition that the raw material properties and reaction severity were basically the same, the performance of SR-1000 catalyst was better than that of PRT-C/PRT-D reforming catalyst and can meet the needs of long-term stable operation of semi-regeneration catalytic reforming unit. The start-up method of SR-1000 catalyst is simple, safe and environmentally friendly.
