ABSTRACT:
Solid waste is fed to a confined zone under pressure and contacted with hydrogen containing gas. Partial conversion of the solid waste to methane occurs and the methane containing gas mixture is removed from the confined zone; it is subsequently purified and methanated so as to be a replacement for natural gas. The remainder of the solid waste is discharged from the confined zone as a carbon containing char which is delivered to a separate reaction zone where it is contacted with steam and oxygen under pressure to convert it to synthesis gas (a mixture of hydrogen, water vapor, carbon monoxide and carbon dioxide). The synthesis gas is drawn from the reaction chamber and serves as the hydrogen feed gas into the confined zone. Between the two zones, metal and glass are separated from the char by virtue of their much higher density than the carbonaceous char by entrainment of the char in a jet of steam.
