British Patent 270,705, May 10, 1926. Chem. Age, vol. 17, 1927, p. 64; Chem. Abs., vol. 22, 1928, p. 1672. Water gas or other gas containing H2 is heated in the presence of metal carbonyls, such as those of Fe, Co, Ni, and Mo, to a temperature, suitably about 240º with H2 and Fe carbonyl, sufficient to decompose the carbonyl. Substances such as NH3 may be added to facilitate the process. The liberated metal may be separated in dust chambers and the issuing gas treated with active silica to adsorb hydrocarbons. |
