AbstractSolid organic wastes are slurried with hot coker recycle feed or fresh petroleum feedstocks at temperatures within the range from about 300° to 1000° F and the resulting mixture is coked to produce gas, oil, and coke. The oil can be used as clean liquid fuel, but preferably it is used as catalytic craker feed since it is a particularly suitable cracking stock and produces high yields of gasoline. This process affords a low-cost waste disposal method by a process compatible with current petroleum refining technology.
