RC Series Continuous Reforming Catalyst
Application
Continuous reforming units
Description
Featured by the high selectivity, the low coke make rate, RC series catalysts are suitable for processing
straight run naphtha, hydrocracking heavy naphtha, cracking gasoline, coking gasoline, condensate oil
and etc. in the continuous reforming unit for high octane gasoline, aromatics and hydrogen.
RC011 (or in laboratory name “PS- Ⅵ”) has low carbon deposition rate and high selectivity, which can
be used in various continuous reforming processes with good feasibility, such as UOP, AXENS, SLCR,
SCCCR and etc.
RC191 (or in laboratory name “PS-Ⅷ”) is the high bulk density catalyst. By introducing the additives
and adjusting the acid function and metal function of the catalyst, it overcomes the limitation of
pinning effect so as to reach the high feed space velocity. By optimizing the pore volume and pore size
distribution of the carrier, it increases the bulk density of the carrier. By optimizing the catalyst formula,
the platinum content is reduced to 0.24w%. Hence under the condition of the same loading volume,
the platinum consumption amount of RC191 is comparable to that of the conventional low bulk density
catalyst.

the gasoline yield increases by more than 1.5%, the carbon deposition rate reduces by more
than 30%. It shows the higher activity and selectivity, stability and regeneration performance.
