ABSTRACT:
An improved reactor system for hydrocarbon processing, employing an external catalyst cooler ("ECC") for dehydrogenating and cracking an alkane stream by contacting it with a fluid catalytic cracking ("FCC") catalyst to produce olefins. Advantageously, these olefins are then oligomerized to gasoline in a single zone of a fluid bed crystalline zeolite oligomerization catalyst, the bed operating in the turbulent regime.
