本发明涉及一种醋酸加氢制乙醇联产乙酸乙酯催化剂及制备方法,主要解决现有技术中醋酸转化率较低、乙醇和乙酸乙酯的选择性不易调变的问题。本发明通过采用一种醋酸加氢制乙醇联产乙酸乙酯催化剂,包括组分a、b、c和载体;所述组分a选自铁、镍、钴、铜、铼、锡、铟、锗、铅或其氧化物中的至少一种;所述组分b选自铱、铂、钯、钌、铑或其氧化物中的至少一种;所述组分c选自磷、铌、钨、钙、钾、
The invention relates to a catalyst for hydrogenation of acetic acid to ethyl alcohol and a preparation method thereof, and mainly solves the problems that the prior art has low conversion rate of acetic acid and difficult selectivity of ethanol and ethyl acetate. In the invention, an ethanol-coproducing ethyl acetate catalyst is prepared by adopting a hydrogenation of acetic acid and comprises components a, b, c and a carrier; the component a is selected from the group consisting of iron, nickel, cobalt, copper, rhenium, Germanium, lead or an oxide thereof; the component b is at least one selected from the group consisting of iridium, platinum, palladium, ruthenium, rhodium or oxide thereof; the component c is at least one selected from the group consisting of phosphorus, niobium, Tungsten, Calcium, Potassium,
