摘要: 在合成气(CO+H2)催化转化反应中,含适当助剂(如Mn、Fe、V等)的负载型Rh催化剂能够有选择地催化生成C2含氧化合物,某些氧化物载体本身也会成为Rh催化剂的助剂[1~3].

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
