Catalyst for producing ethyl alcohol and co-producing ethyl acetate through acetic acid hydrogenation and preparation method

The invention relates to a catalyst for producing ethyl alcohol and co-producing ethyl acetate through acetic acid hydrogenation and a preparation method and mainly solves the problems that in the prior art, the acetic acid conversion rate is low, and selectivity of ethyl alcohol and ethyl acetate is not easy to modulate. The catalyst for producing ethyl alcohol and co-producing ethyl acetate through acetic acid hydrogenation comprises a component a, a component b, a component c and a carrier; the component a is selected from one or more of iron, nickel, cobalt, copper, rhenium, stannum, indium, germanium, lead or oxide of lead; the component b is selected from one or more of iridium, platinum, platinum, ruthenium, rhodium or oxide of rhodium; the component c is selected from one or more of phosphorus, niobium, tungsten, calcium, potassium, sodium, barium, strontium or oxide of strontium. By means of the technical scheme of the catalyst and the preparation method thereof, the mentioned problems are well solved, and the catalyst and the preparation method thereof can be used for producing ethyl alcohol and co-producing ethyl acetate through acetic acid hydrogenation.
