The Occidental Flash Pyrolysis Process

  • Ping Wu Chang

In 1968, the Occidental Research Corporation, formerly the Garrett Research and Development Company, initiated a program to recover metals and glass from municipal solid waste (MSW) and to convert the organic portion to a fuel oil by Flash Pyrolysis®. The efficacy of the Flash Pyrolysis was established in a 1.4 kg/hr scale laboratory reactor.(1,2) Waste feed, in addition to MSW, includes tree bark, rice hulls, animal manure, rubber,(3) and sewage sludge.(4) The pyrolysis process was then successfully tested in a 3.6 ton/day pilot plant where the major process variables were investigated, material handling problems resolved, and sufficient products produced to permit characterization.
