Abstract:
1394852 Decomposing polymers into liquids and gases NIIGATA TEKKOSHO KK 5 May 1972 [18 Aug 1971] 46774/74 Divided out of 1394851 Heading C5E Apparatus for decomposing high polymers into liquid and gaseous fuels comprises an extruder 11 having a rotatable screw shaft 13 and a nozzle 30, a heated tank 36 connected to the end of the nozzle 30, a rotary pump 38 for reducing the pressure in the tank 36, and a sink and float tank 40 for storing gaseous and liquid fuel produced by decomposition of the polymer. The fuel produced is in part passed to a combustion apparatus 44 and in part passed to a burner 47 which is coupled to a gas- or steamturbine 48 connected to an electrical generator 49. The polymer is progressively heated to 160-400 C. by the heater 14a, to 400-600 C. by the heater 14b and to 600-1000 C. by the heater 14c. The tank 36 is heated by exhaust gas from the burner 47 which passes through the pipe 37.
