ABSTRACT:
A process for converting organic waste into reusable hydrocarbons and a system for doing so, the system including a feeding mechanism for the waste, a reactor and a residue-disposing mechanism. The waste is to be fed into the reactor in which a molten lead bath is confined in an oxygen-free atmosphere. The system is used to practice a process for the pyrocatalytic conversion of the waste, which process comprises, feeding the waste into a reaction zone of a pyrocatalytic reactor, the waste being essentially free of a halogenated synthetic resinous material, and mixing the waste with a minor proportion by weight of a particulate catalyst in the bath held at a temperature in the range from about 450° C. to 550° C. in an elongated vat. The catalyst consists essentially of a major proportion by weight of particulate bauxite <2 mm, in combination with a minor proportion of aluminum powder <0.1 mm having a minimum nominal aluminum content of at least 95%, preferably at least 98%, and a Fe content of less than 0.5% and Si less than 0.2%. Between the feed-inlet or “charging” end of the vat where waste from the feeding mechanism enters and the “residue-discharging” or “discharging” end of the vat where the residue is delivered to the residue-disposing mechanism, a combination of plural rotating drums with radially protruding fingers in cooperation with gratings, provide the necessary mixing and urging action and contact time.
