We've earlier documented that Carbon Monoxide can be catalytically condensed, via reactions with Water, H2O, and thus be chemically transformed into liquid hydrocarbons.
A few examples of that reportage would include:
Standard Oil Carbon Monoxide + Water = Gasoline | Research & Development; wherein is described: "United States Patent 4,559,363 - Process for Reacting Carbon Monoxide and Water; 1985; Claims: A method for the production of hydrocarbons by reacting carbon monoxide and water"; and:
Pittsburgh 1951 Carbon Monoxide + Water = Hydrocarbons | Research & Development; which discloses: "United States Patent 2,579,663 - Process of Synthesizing Hydrocarbons; 1951; A ... process for synthesizing hydrocarbons; more particularly the invention relates to a process for synthesizing normally liquid hydrocarbons from carbon monoxide and steam".
