A fluid coking process is provided in which a stream of heavy oil product, which typically is recycled to the coking zone, is first subjected to solvent separation to separate it into a high Conradson carbon product and a lower Conradson carbon product and, thereafter, at least a portion of the lower Conradson carbon product is recovered and the high Conradson carbon product is recycled to the coking zone.

The present invention features the use of a particulate sorbent and a particulate FCC catalyst, which are physically separable, sequentially in the same FCC riser, followed by separation of commingled spent catalyst and sorbent particles from vapors, and the subsequent primary partial regeneration and heat up of spent sorbent particles and catalysts particles in an oxygen deficient burning zone, followed by physical separation of partially regenerated catalyst and sorbent particles, preferably using a cyclonic classifier to effect the separation. This is followed by secondary regeneration of the resulting segregated partially regenerated sorbent and catalyst streams in oxygen rich combustion zones to fully regenerate sorbent and catalyst particles.

A delayed coking process is provided in which the fresh oil is introduced into the coker product fractionator and in which a stream of heavy oil product is withdrawn from the fractionator before it can contact the fresh oil. The stream of heavy oil product withdrawn from the fractionator is subjected to solvent separation to produce a high Conradson carbon product and a low Conradson carbon product. At least a portion of the low Conradson carbon product is recovered and the high Conradson carbon product is recycled to the coking zone.
