Higher mixed alcohols are produced from syngas contacting a catalyst in a reactor. The catalyst has a first component of molybdenum or tungsten, a second component of vanadium, a third component of iron, cobalt, nickel or palladium and optionally a fourth component of a promoter. The first component forms alcohols, while the vanadium and the third component stimulates carbon chain growth to produce higher alcohols.
