Abstract: Methods and systems for enhancing hydrocarbon processing in a fluid catalytic cracking (FCC) unit by introducing a renewable feedstock into the FCC unit at alternative locations of the FCC unit to increase residence time and promote a higher degree of FCC feedstock cracking. The renewable feedstock may include one or more of plastic-derived pyrolysis oil or plastic-derived hydrocarbons, biomass-derived pyrolysis oil, municipal waste-derived pyrolysis oil, vegetable based feedstock, animal fat feedstock, algae oil, sugar-derived hydrocarbons, or carbohydrate-derived hydrocarbons. The alternative locations of the FCC unit may include one or more of FCC reactor catalyst bed, an FCC catalyst stripper, at a nozzle located downstream of a gas oil injection point, or at a nozzle located upstream of the gas oil injection point.

Abstract: A system for processing a selected feedstock using a catalyst includes a reactor, a catalyst recovery system, and a conduit. The reactor receives the catalyst and the selected feedstock. A reaction between the selected feedstock and the catalyst generates a spent catalyst. The catalyst recovery system processes the spent catalyst. The conduit connects the reactor to the catalyst recovery system and has a lateral section. The spent catalyst flows from the reactor through a flow space defined by an inner wall of the lateral section to the catalyst recovery system. The system also includes a fluidizer positioned at the lateral section. The fluidizer includes at least one nozzle. The at least one nozzle is completely inside the flow space. The at least one nozzle forms and directs a jet of a fluidizing agent into the spent catalyst in the lateral section.

Abstract: A process for catalytic cracking of hydrocarbon oils includes the step of contacting a hydrocarbon oil feedstock with a catalytic cracking catalyst in a reactor comprising a dilute-phase transport fluidized bed and a fast fluidized bed connected in series for reaction. In the fast fluidized bed, the axial solid fraction ε of the catalyst is controlled within the range of about 0.1 to about 0.2. When used for catalytic cracking of hydrocarbon oil feedstocks, particularly heavy feedstock oils, the process and system show lower yields of dry gas and coke, and good product distribution.

Abstract: Systems and methods for enhancing the processing of hydrocarbons in a FCC unit by introduction of the coked FCC catalyst from the FCC reactor and a renewable feedstock to the FCC regenerator to facilitate regeneration of the coked FCC catalyst. The renewable feedstock can contain biomass-derived pyrolysis oil. The biomass-derived pyrolysis oil and coke from the coked FCC catalyst are oxidized by oxygen to provide a regenerated catalyst that is recycled to the FCC reactor.

Abstract: A process and apparatus for catalytically cracking fresh heavy hydrocarbon feed to produce cracked products is disclosed. A fraction of the cracked products can be obtained to re-crack it in a downer reactor. The downer reactor may produce high selectivity to light olefins. Spent catalyst from both reactors can be regenerated in the same regenerator.
