Abstract
Abstract Ethanol is prepared with high selectivity by the catalytic reaction of carbon monoxide and hydrogen. The catalyst composition comprises: (A) catalyst component consisting of (a) a rhodium component, (b) a lithium component, and (c) a component of at least one element selected from the group consisting of iridium, manganese, scandium, mangesium, yttrium, ytterbium, lutecium, vanadium and chromium; and (B) catalyst component, which is supported on a separate carrier from said (A) catalyst component, being selected from the group consisting of (a) an iron component and a component of at least one element selected from the group consisting of iridium and palladium, (b) a molybdenum component and a component of at least one element selected from the group consisting of iridium and palladium, (c) an iron component, a molybdenum component and a component of at least one element selected from the group consisting of iridium and palladium, and (d) a copper component and optionally a component of at least one element selected from the group consisting of zinc and chromium.
