Abstract

Three MO precursors, (NH₄)₆Mo₇O₂₄,H₃PMo₁₂O₄₀ and MoO₂(acac)₂ (acacH is acetylacetone), have been used to prepare SiO₂-supported Mo catalysts. SiO₂ was pretreated with either KCl or K₂CO₃. The effects of these Mo precursors on the activity and product selectivity of the Mo catalysts in CO hydrogenation were examined at 16 kg cm^-2 and 573 K. Selectivity for alcohols vs hydrocarbons was greatly influenced by the precursors and K salts. Catalysts prepared from (NH₄)₆Mo₇O₂₄ and supported on KCl-treated SiO₂ had the highest activity and selectivity for alcohols. Catalysts repared from MoO₂(acac)₂ produced mainly hydrocarbons. The observed changes in activity and selectivity with preparation method seem to be governed by the oxidation state of Mo.
