Pyrolysis system utilizing pyrolytic oil recycle

摘要

A pyrolysis process and system produces a solid residue and a clean, enriched fuel gas. In the process, the pyrolytic oil and filter cake are recycled in such a manner as to produce products of optimal value, and to minimize the need for servicing and downtime of the system. Recycling of water recovered in the process may also be employed to achieve enrichment of the gaseous product. The process may be carried ou in such a manner as to produce a non-polluting wastewater stream that can be discharged directly from the system.
