This report describes a thermochemical process through which organic waste materials found in municipal trash are converted into a high grade gasoline product. The process involves three major steps: selective pyrolysis to form gases relatively rich in olefins such as ethylene, propylene, and butylene; compression and purification of the pyrolysis gases to concentrate the olefins; and polymerization of the olefins to form polymer gasoline. Pyrolysis experimentation has resulted in about half of the energy in the organic feed being found in the gaseous olefin pyrolysis product. Polymerization of pure ethylene has produced a synthetic crude oil product containing about 90% gasoline having an unleaded motor octane of 90. Preliminary economic evaluation has shown the process to be suitable for relatively small plant sizes. The projected yield of gasoline and oils is about 0.19 l/kg (46 gal/ton). The process is currently in the bench-scale development stage. (Author)
