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 diluted with hot solids from the heater then passed to the scrubbing zone of the coker reactor. A light paraffin stream is introduced into this stream of hot solids between the point where the heater solids are introduced and the scrubbing zone. The hot particles act to catalyze the dehydrogenation of the paraffins to olefins.
