Integrated catalytic cracking process with light olefin upgrading

Patent ·
OSTI ID:6039727
This patent describes an improvement in a fluid catalytic cracking process. The process comprises admixing a hydrocarbon oil feed with hot regenerated catalyst in a bottom portion of a reactor riser with a light hydrocarbon lift gas, passing the mixture of the hydrocarbon oil feedstock, catalyst and lift gas through the riser, thereby volatilizing the oil feed and effecting cracking thereof at the process temperature under endothermic process conditions and deactivating the catalyst by deposition of carbonaceous deposits thereon, separating the deactivated catalyst from the cracked hydrocarbonaceous feed, passing the deactivated catalyst to a regenerator vessel wherein the carbonaceous deposits are removed from the deactivated catalyst under exothermic process conditions by means of a regenerating medium introduced into the regenerator vessel, and passing the regenerated hot catalyst substantially above process cracking temperature to the bottom section of the reactor riser.
