Relates to the manufacture of gas by air-blasting an ignited fuel bed to bring it to incandescence, separately introducing a hydrocarbon material into a stream of superheated steam, and thoroughly mixing and heating the steam and hydrocarbon material to > 540°, introducing the heated gaseous product into the incandescent fuel bed from above, and removing the resulting gas from beneath. The gas generated contains 2.0-3.5 times as much H₂ as CO and is substantially free from suspended C resulting from pyrolysis of the hydrocarbon material. Describes apparatus.
