(JP7041773-A)      Appts. for converting thermoplastics waste into oil by thermal decomposition consists essentially of a reactor (1) in which a heated plastics melt (21) is stirred while decomposition gases are extracted for further processing through discharge duct (6). Reactor (1) has a semi-spherical base and is mounted on furnace (4) which is heated by burner (5) to a temperature sufficient to melt and decompose plastic waste supplied from hopper (8). The melt (21) is agitated by a base-shaped multi-blade stirrer (14) on hollow shaft (19) and driven by motor (13) through gears (11, 12). Non-plastics matter (22) such as metal or glass collects by gravity at the reactor base centre and is extracted periodically through suction pipe (15) and discharge duct (23) under vacuum supplied by pump (20). The matter collects in container (2). Thermal decomposition gases from melt (21) are extracted through duct (6) and pass to known catalyst processes for further decomposing hydrocarbons. The resulting gas is cooled and forms a light oil condensate.    USE -   The appts. produces a useful oil prod. from mixed and impure plastics waste.    ADVANTAGE -   Extraneous matter can be extracted without halting the process or cooling the reactor, so improving efficiency and saving energy.
