Abstract
A fluid coking process is provided in which a carbonaceous feed is first coked in a dense fluidized bed first coking zone and the effluent of the dense bed is passed as a suspension through a transferline second coking zone. A major portion of the solids is separated from the effluent of the upper end of the transferline and passed to a third coking zone which is operated at a higher temperature than the other coking zones and in which the first and second coking zones are positioned.
