ABSTRACT:
The liquid yield of a delayed coking process is improved by controlling the temperature of the vapor space above the carbonizing mass so that that incipient coking and cracking of the vapors is reduced. The temperature is preferably controlled by introducing a quenching liquid into the vapor space; suitable liquids for this purpose include water, coker feedstock and the bottoms fraction derived from the coker products.
