ABSTRACT:
A solid catalyst composition for the vapor phase conversion of methanol and ethanol to higher linear primary alcohols (e.g., n-propanol) is made up of particles of an inert, high surface area support (e.g., gamma-aluminum oxide) impregnated with an inorganic base promoter (e.g., a basic salt of an alkali metal) and a platinum group metal (e.g., rhodium). The production of the higher linear primary alcohols is carried out by contacting a mixture of methanol, ethanol, and a carrier gas (e.g., synthesis gas) with the catalyst at a temperature of between 200.degree. and 400.degree.C. and pressure of between 1000 and 5000 p.s.i.g. at a space velocity of between 2000 and 10,000 hr.sup.-.sup.1.
