Coking Apparatus and Process for Oil-Containing Solids

A coking process, comprising:

• providing oil-containing solids suitable for introduction into a riser;
• injecting a fluidizing medium into said riser;
• feeding said oil-containing solids into said riser;
• contacting said oil-containing solids with a hot stream of solids;
• cracking a portion of the hydrocarbons from said oil-containing solids;
• separating gaseous products from said oil-containing solids in a separator vessel;
• transferring coked oil-containing solids into a gasifier;
• introducing a stream of gas comprising oxygen-containing gases into said gasifier;
• recovering syngas from said gasifier;
• recycling a hot stream of solids from said gasifier to said riser;
• converting said syngas to hydrogen using a water gas shift reaction;
• hydroprocessing a hydrocarbon using said hydrogen;
• and
• wherein the concentration of oil in said oil-containing solids entering said riser is greater than in a hot stream of oil-containing solids exiting said riser.

An apparatus for coking, comprising:

• a grinding device for producing oil-containing solids of appropriate size;
• a riser having an inlet for introducing said oil-containing solid;
• a separator vessel in communication with an exit of said riser;
• and
• a transfer conduit for transporting coked oil-containing solids from said separator vessel to a gasifier;
• said gasifier having an outlet for releasing syngas and a recycle standpipe.
