Production of Gas Comprising Hydrogen and Carbon Monoxide. United States Patent 2,578,475. Dec. 11, 1951. Chem. Abs., vol. 46, 1952, p. 2271. Gas mixture with a high ratio of H2 to CO is secured by introducing into a spark-ignition internal-combustion engine a mixture of a hydrocarbon gas, such as natural gas with O2 such that the molecular ratio of O2 to natural gas varies 0.75-0.9:1. This mixture is compressed and ignited just before the top of the stroke. Gives an equation for determining desirable relations between pressure and gas-O2 ratios. The products are quickly released to atmospheric pressure; this cools them so that no further reaction occurs. H2-CO ratios as high as 1.6:1 can be obtained in this manner. |
