POLYMER WASTE PROCESSING METHOD Russian patent published in 2003 - IPC

Abstract RU 2213107 C2

FIELD: waste disposal. SUBSTANCE: invention relates to a method for chemical processing of industrial and domestic organic polymer wastes into motor fuel and chemical raw material. Processing comprises thermal fluidization of waste in reactor at working temperature and elevated pressure in solvent to yield liquid products. Liquid fraction is separated from solids and distilled. Cyclic processing is conducted on installation provided with at least one additional reactor wherein processing operation is time-shifted, that is, in thermal fluidization stage, each of reactors additionally receives part of hot products from thermal fluidization stage of the other reactor. EFFECT: simplified technology and increased yield of light fractions with boiling temperature up to 200 C. 8 cl, 3 dwg
