ABSTRACT:
A heavy high-sulfur hydrocarbonaceous feedstock is partially delayed coked and partially formcoked. The coke products are screened, with larger particles being calcined at desulfurizing temperatures and smaller particles being recycled to the formcoker. Overhead products from both coking operations are combined, fractionated, and desulfurized. The heaviest cut from the fractionator is combined with the feedstock as recycle.
