1. A process for producing a coke-containing fuel, comprising coking a carbonaceous material in the liquid phase under a pressure of 300 to 3200 psig at a temperature of 400°
- to 700°
F for 0.5 minutes to 3 hours to form gases, hot liquid and liquid-containing coke;
separating said coke from said liquid and gases;
drying said coke by extraction with a combustible hydrocarbon under a pressure of between 300 and 3200 psig at a temperature of between 400° and
700°
F to remove said liquid from said coke and form a hydrocarbon solution of water and a dense slurry of dry coke in said hydrocarbon suitable for burning.

Abstract
Disclosed is a process for making a hydrocarbon coke slurry fuel by coking carbonaceous materials in the liquid phase under autogenous pressure to form coke which is then extracted with a combustible hydrocarbon at high temperatures and pressures to produce a dense slurry of coke in the hydrocarbon suitable for use as a fuel.
