Abstract
Catalyst for the production of methane from carbon and/or coal by means of catalytic gasification. The catalyst compostion containing at least two alkali metal salts. A particulate carbonaceous substrate or carrier is used.
Claims5
A catalyst for use in the process of producing methane from particulate carbonaceous material, comprising a catalyst composition deposited on surface portions of said particulate carbonaceous material and formed of a mixture of alkali metal salts consisting essentially of at least one of an alkali metal carbonate and an alkali metal sulfate together with at least one of an alkali metal halide and an alkali metal carbonate differing from the first-mentioned alkali metal carbonate, said catalyst composition being prepared from a solidified melt of said mixture of alkali metal salts formed prior to being deposited upon said particulate carbonaceous material and with the alkali metal salts forming said mixture each being in a concentration adequate to render the resulting catalyst composition eutectic.
