  • Method for decomposition of polymers into fuels
    Patent number: 3947256
    Abstract: A method for treating high polymer wastes in such a way that pollution of the atmosphere will be avoided. Solid high polymer bodies are subjected to simultaneous compression and shearing action until they reach a state of fusion and decompose at least in part into a fluid state. The fluid is then directed to a location where it is available as a fuel. A rotary feed screw is situated in a cylinder to coact therewith for providing compression and shearing of high polymer bodies until they reach a state of fusion. Then the fused material is subjected to a decomposing action in order to decompose into a fluid condition, and the resulting fluid is conveyed to a location where the fluid is available for further use.
