Patent number: 4373995Abstract: 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.Type: GrantFiled: October 5, 1981Date of Patent: February 15, 1983Inventors: Mack D. Bowen, Kenneth R. Purdy

Patent number: 4145256Abstract: A carbonaceous residue or char having novel properties is produced from particulate agricultural waste material, such as peanut shells, which upon heating exhibits an exothermic decomposition into an off gas component and a solid component in which the off gas component is more highly reactive to oxygen than is the solid component. By introducing air into the reaction zone whereat the decomposition is effected and controlling the amount of air so introduced such that not all of the off gas component may be oxidized, the preferential reaction of the air with the off gas component will protect the solid component from any significant oxidation while at the same time it will elevate the temperature in the reaction zone sufficiently to effect substantially complete decomposition of the material so that the recovered product is of very high carbon content. At the same time, a temperature gradient is established in the reaction zone which will allow some of the vapor component of the decomposition (i.e.Type: GrantFiled: December 2, 1976Date of Patent: March 20, 1979Assignee: Georgia Tech Research InstituteInventor: Mack D.
