Particulate coke and raw sewage are mixed and conveyed as a slurry through series connected, pressure sealed chambers into which super-heated steam is injected to convert the mixture into a molten mass depleted of noxious gases and volatiles. The molten mass is compacted while exposed to reactive hydrogen gas to form an enriched solid fuel log.

In a process for producing a solid fuel from a slurry formed from raw sewage and particulate coke, the steps of: conducting said slurry through a plurality of pressure sealed zones in series; physically agitating the slurry during movement through said zones; injecting super-heated steam into said zones during said movement of the slurry therethrough to release only non-noxious gases and volatiles leaving a liquid depleted residue; compacting the residue discharged under pressure from the zones within a reaction zone; injecting hydrogen gas into the reaction zone during compaction of the residue to form a compacted mass; and cooling said compacted mass to form the solid fuel product. A method of continuously treating raw sewage and enriching a relatively low energy content solid fuel, comprising the steps of: grinding said solid fuel into particles; mixing said particles with the raw sewage to form a slurry; mixing the slurry during movement with super-heated steam until non-noxious gases and volatiles are evolved therefrom, leaving a liquid depleted mass; exposing said mass to a reactive gas other than steam; and compacting said mass into a solid fuel product.
