Enhancing hydrocarbon processing in fcc unit with renewable feedstock
A recently granted patent (Publication Number: US11970664B2) discloses a system for processing gas oil in a fluid catalytic cracking (FCC) unit. The system includes a reactor with an FCC reaction zone to crack the gas oil stream in the presence of steam and an FCC catalyst, a regenerator to oxidize coke on the coked FCC catalyst and biomass-derived pyrolysis oil, and a controller to adjust the amount of pyrolysis oil based on temperature indications to maintain optimal cracking and oxidation temperatures. The system also features a temperature sensor, a stripping zone to remove hydrocarbons from the coked catalyst, and various configurations for introducing the biomass-derived pyrolysis oil into the regenerator.
Furthermore, the patent describes a method for processing gas oil in an FCC system, involving mixing the gas oil with steam and an FCC catalyst, cracking the gas oil to produce hydrocarbon products, separating the coked catalyst, and supplying it to the regenerator along with biomass-derived pyrolysis oil. The method includes adjusting the pyrolysis oil amount based on temperature readings to ensure efficient cracking and combustion processes. Additional steps involve introducing the pyrolysis oil at specific locations within the system and maintaining an effective hydrogen index for the oil. Overall, the patent highlights a comprehensive approach to optimizing gas oil processing in an FCC system through controlled biomass-derived pyrolysis oil addition and temperature management.
