ABSTRACT:
An integrated fluid coking/paraffin dehydrogenation process. The fluid coking unit is comprised of a fluid coker reactor, a heater, and a gasifier. Solids from the fluidized beds are recycled between the coking zone and the heater and between the heater and the gasifier. A separate stream of hot solids from the gasifier is passed to the scrubbing zone or to a satellite fluidized reactor. A first stream containing an effective amount of C.sub.1 to C.sub.2 paraffins is introduced into this stream of hot solids between the point where the diluent is added and the scrubbing zone. The hot particles act to catalyze the dehydrogenation of paraffins to olefins. A second stream containing C.sub.3 to C.sub.10 paraffins is introduced downstream of the introduction of said first stream.
