Abstract
Hydrogen cyanide is removed from an HCN containing gas, e.g., a gas containing CO+H.sub.2, by contact with a metal oxide catalyst comprised of the oxides of molybdenum, titanium, and aluminum in the presence of water vapor, and subsequently water washing the resulting gas.
Claims11
A process for reducing the HCN concentration of HCN containing gases containing less than 10 wt ppm sulfur comprising treating the gas, in the presence of water vapor and at HCN removal conditions with a catalyst comprising alumina and the oxides of molybdenum and titanium, wherein said catalyst is treated with hydrogen and at least a portion of the oxides of molybdenum and titanium are in a reduced valence state, the treating taking place in the substantial absence of Group VIII metals or compounds.
