Catalyst and its use

A catalyst particularly effective for producing mixed alcohols in high yields and with good selectivity from synthesis gas, eg for gasoline blending, is produced by contacting ammonium thiomolybdate with an active carbon support so as to deposit MoS 3 , depositing a potassium compound, and activating by heating the catalyst in a reducing atmosphere.
