ABSTRACT:
The operation of FCC apparatus is improved by decreasing oil partial pressure in the FCC reactor riser by about 10 psia, as compared to the normal oil partial pressure in the riser, thereby increasing octane rating of the gasoline produced in the FCC unit. The oil partial pressure may be reduced by injecting a suitable amount of an inert diluent into the riser, or by decreasing throughput of the FCC reactor.
