Abstract:
A method and system for increasing olefin production and quality from a hydrocarbon feed comprising a fully integrated multi-stage catalyst regeneration zones with multi-stage reaction zones in series and/or parallel. The multi-stage regeneration with at least one partial and one full burn zone provides an independent control to achieve the lowest possible regenerated catalyst temperature, resulting in highest possible catalyst to oil ratio required to maximize olefins yields through increased catalytic cracking in a multi stage FCC riser/risers.

Claim (Index 1):
A method for increasing olefin production from a hydrocarbon feed, said method comprises: a) delivering from a multi-stage catalyst regenerator a partially-regenerated catalyst from at least one catalyst partial regeneration zone to a secondary riser reactor and a fully-regenerated catalyst from at least one catalyst full regeneration zone to a primary riser reactor; b) cracking the hydrocarbon feed in a first reaction zone of the primary riser reactor to produce a first cracked product including olefins and spent catalyst and passing the first cracked product and spent catalyst to a bed cracking reaction zone in a reactor vessel to produce a second cracked product; c) separating the first and second cracked products from the spent catalyst in the reactor vessel; d) recovering the first and second cracked products including olefins and separating an uncracked bottoms and a partially cracked product(s) from the cracked products; e) cracking a recycle feed comprising at least one of the uncracked bottoms, partially cracked, and cracked products of step (d), in the secondary riser reactor to produce a third cracked product and additional spent catalyst; f) separating and recovering the third cracked product comprising olefins from the additional spent catalyst and delivering the additional spent catalyst to the reactor vessel; and g) passing the spent catalyst from the reactor vessel to the multi-stage catalyst regenerator comprising the catalyst partial regeneration zone and the catalyst full regeneration zone, wherein the spent catalyst is partially regenerated to provide the partially-regenerated catalyst and a portion of the partially-regenerated catalyst is delivered to the catalyst full regeneration zone to provide fully regenerated catalyst.
