Selective One Step Synthesis of Acetic Acid from Syngas over Rh/NaY Catalyst

Abstract

Abstract: Rhodium catalyst entrapped in the supercages of NaYzeolite(Rh/NaY) was used for syngas conversion at 1.0MPa and 250 ℃. It was shown that the catalyst was highly stable and selective for a direct synthesis of acetic acid. The selectivity of acetic acid was about 50% with a syngas that contains equal moles of CO and H₂The selectivity increases up to 70% when n(CO)/n(H₂)=3. No formation of ethanol was detected under steady catalysis, and the formation of all other C₂oxygenates was below 5%.

Key words: Rhodium catalyst, Zeolite, Syngas, Acetic acid, Rh/NaY
