Integrated fluid coking/paraffin dehydrogenation process
Abstract:
The present invention relates to 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 a satellite reactor. A light paraffin stream is introduced into directly into this stream of hot solids passing to the satellite reactor or into the satellite reactor. The hot particles act to catalyze the dehydrogenation of the paraffins to olefins.
