ABSTRACT:
An improved fluid coking process which includes: (a) a fluid coker comprised of a coking zone, a scrubbing zone, and a stripping zone; (b) a heater, and optionally a gasifier. The improvement comprises feeding a portion of the heated solids from the heater and/or the gasifier, to the stripping zone. Consequently, the coking zone can be operated at a temperature lower than the stripping zone.
