NEW REFORMING CATALYST DEVELOPED BY RIPP

To meet the demands for high-octane gasoline and aromatics, catalytic reforming process has been advancing quickly in China. The reforming catalysts developed by RIPP have been used in more than 80% capacity of domestic CCR and SR units. This paper introduces the properties of PS-VI CCR catalyst developed by RIPP in recent years and also the result from commercial units. The PS-VI catalyst has high activity and good selectivity, under the same reaction conditions, the carbon on catalyst was lowered by 26% in mass as compared with that of the reference catalyst. Among the SR reforming catalysts, the new type of PRT series catalysts have excellent performance at low reaction pressure compared with the ref. Cat A. The aromatics and reformate mass yields of PRT catalyst were 2%～3% and 3%, respectively, higher than those of Cat A, and the run length was 30%～40% longer as well, which exhibits good prospect of application.
