    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.

    Abstract translation: 提供了一种流体焦化方法，其中碳质进料首先在致密的流化床第一焦化区中焦化，并且致密床的流出物作为悬浮液通过传输线第二焦化区。 固体的主要部分与传输线上端的流出物分离，并通过第三焦化区，其在比其它焦化区更高的温度下操作，其中第一和第二焦化区位于该第三焦化区。

    Abstract: In a fluid coking process, a gas containing coke particles is elutriated in a riser portion of a vessel to remove selectively the larger coke particles. The elutriated gas flows into a bed of solids positioned in the upper portion of the vessel.
