A process and apparatus for gasification of organic materials (typically incorporated in domestic and industrial wastes, including auto shredder residues) to produce useful synthesis gas (primarily CO & H2) with effectively non-toxic ash residue by means of a preferably stoichiometric burner directed into a single stage reactor containing a tumbling charge thus heated to 650 to 800°C (below the incipient fusion temperature of the charge) resulting in thermally cracking and gasifying the organic materials in the charge and reacting the complex hydrocarbons and gas evolved with the CO2 and H2O generated by the burner by combustion of a fuel and oxygen-containing gas at a high flame …

Why it's free to use
- Filed May 6, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 6, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 6, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
