Abstract
In a fluid catalytic cracking (FCC) process and apparatus, the heat balance between the reactor and the regenerator of the FCC operation is partially uncoupled by transferring at least a portion of thermal energy from the reactor vessel riser to the regenerator vessel. The transfer of thermal energy results in a higher regenerating temperature. The thermal energy is recirculated to the bottom section of the reaction riser through a regenerated catalyst having higher temperature. Consequently, the outlet of the reaction vessel is maintained at a substantially constant temperature (e.g., 100.degree. F.) and the rate of conversion of the oil feed and the octane number of gasoline produced in the process are increased.
