methanation|mɛθəˈneɪʃən|
[f. methane + -ation.]
Conversion (esp. of carbon monoxide and hydrogen) into methane.
1956M. Greyson in P. H. Emmett Catalysis IV. vi. 506 The development of commercial methanation procedures is normally undertaken on the assumption that means exist, or will exist, for the conversion of coal to mixtures of hydrogen and carbon monoxide. 1969R. F. Lang tr. Henglein's Chem. Technol. 425 This reaction is used for the production of especially high-grade fuel gases from water gas (CO + 3H2 - 48·87 kcal = CH4 + H2O) (methanation) (CO2 + 4H2 - 39·1 kcal = CH4 + 2H2O). 1973Nature 7 Dec. 326/2 It is the catalytic enrichment (a methanation) which is the key to the production of SNG [sc. substitute natural gas] and the Gas Board is loath to reveal the full details of its operation.
Hence (as a back-formation) ˈmethanate v. trans., to convert into methane, to subject to methanation.
1963Dirksen & Linden Pipeline Gas from Coal by Methanation of Synthesis Gas (U.S. Inst. Gas Technol. Res. Bull. No. 31) p. iii, This program established that a variety of nickel catalysts were capable of methanating synthesis gas to 900 Btu/SCF pipeline gas. 1974Sci. Amer. Apr. 9/3 Methanating animal wastes from feed-lots in the Middle West is probably the best application of this idea. |
