Abstract: An integrated fluid coking/paraffin dehydrogenation process. The fluid coking unit is comprised of a fluid coker reactor and a heater with hot solids recycling between the coker reactor and the heater. A light paraffin stream is introduced into the line wherein the hot particles are recycled to the coking zone. The hot particles act to catalyze the dehydrogenation of the paraffins to olefins.

Abstract: Disclosed is a method which combines catalytic cracking and olefin production using a coked catalytic cracking catalyst as a dehydrogenation catalyst to dehydrogenate an alkane feed stream and form an olefin rich product stream. The method uses a staged backmixed regeneration system to form the dehydrogenation catalyst and to fully reactivate deactivated cracking catalyst for reuse in the cracking reaction. The catalyst preferably comprises a crystalline tetrahedral framework oxide component.

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.

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 after first being reduced in temperature by introduction of an effective amount of diluent, such as steam. A light paraffin stream 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.

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.

Abstract: Disclosed is a method which combines catalytic cracking and olefin production using a coked catalytic cracking catalyst to dehydrogenate an alkane feed stream and form an olefin rich product stream. Preferably, the coked catalytic cracking catalyst has a carbon content of about 0.2-10 wt. %. The catalyst preferably comprises a crystalline tetrahedral framework oxide component.
