Abstract:
1. A reactor for the pyrolysis of carbon-containing waste material, which includes: a reactor vessel having a first end wall structure at a first end of the reactor vessel, and a second end wall structure at a second end of the reactor vessel and a cylindrical wall structure extending between said first and second ends of the reactor vessel, the cylindrical wall structure including an inner shell and an outer shell spaced therefrom, the reactor vessel defining an air-tight reactor chamber, and having inlet means through which waste material can be introduced into the reactor chamber to be heat treated and outlet means for discharging heat treated material from the reactor chamber; a support tray that is disposed horizontally within the reactor chamber between the inlet means and the outlet means and that has a support surface for supporting a bed of the waste material; heating means for heating the bed of waste material on the support surface of the support tray, to a temperature sufficient to cause decomposition of the waste material into a gaseous product and a solid residue; a conveyor system for moving the bed of waste material along the support tray; vacuum means for forming a vacuum within the reactor chamber; cooling means in the form of a cooling jacket which is defined between the inner and outer shells of the cylindrical wall structure and in which a cooling medium can flow for cooling at least part of the reactor vessel thereby to provide for condensation of a portion of the gaseous product when it contacts the reactor vessel; and deflector means which is disposed above the support tray for deflecting the gaseous product towards sides of the reactor vessel, thereby to prevent droplets of condensed gaseous product from falling back onto the support tray.
