1399791 Combustible gas TEXACO DEVELOPMENT CORP 21 May 1973 [28 June 1972] 24024/73 Heading C5E A gas containing H 2 and CO is made by simultaneously introducing into a free-flow, unpacked, non-catalytic gas generator: (a) a liquid hydrocarbonaceous fuel containing C, H and optionally other elements, (b) a gas containing at least 22 mol. per cent CH 4 , and (c) a free-oxygen containing gas comprising 0À6 to 1À2 atoms of free oxygen per atom of combustible carbon in the fuel and methane containing gas, allowing partial oxidation to take place in the absence of externally added water and removing from the reaction zone a product gas stream comprising H 2 , CO, H 2 O, CO 2 and particulate carbon. The components are preferably fed into the generator by a burner comprising a central duct for the oxygen containing gas and two further annular ducts concentric therewith for a methine gas/hydrocarbonaceous fuel mixture and a temperature controlling gas, e.g. air, N 2 , generator effluent gas or one reduction off-gas respectively. The hydrocarbonaceous fuel may be liquefied petroleum gas, petroleum distillate fractions, shale or tar sand oil, aromatic hydrocarbons, aldehydes, ketones alcohols or waste organic liquors or a slurry of the above with a solid fuel, e.g. petroleum or coal coke, shale, tar sand or coal.
