ABSTRACT:
This invention relates to a method of cracking polymers, especially waste hydrocarbon polymers to produce products of lower molecular weight. The process comprises feeding the polymer into a processing chamber or circular-cross section which chamber also has a bed of particulate material maintained in suspension and in toroidal shape by a hot gas introduced into said chamber so that the polymer intermingles with the particulate materials of the bed and is cracked into products of lower molecular weight. The invention is useful for converting polymeric wastes into products of commercial value such as e.g. waxes, lubricants and monomeric olefins at the same time reducing environmental pollution.
