摘要
Abstract
The hydrogenation of ethyl acetate to ethanol on a homemade Cu/SiO2 catalyst based on small-scale test was investigated through model test. The effects of temperature,pressure, WHSV and mole ratio of H2to ethyl acetate on the performances of the catalyst in the hydrogenation were researched. The stability test for 1 000 h was completed. The fresh and used catalysts were characterized by means of BET,XRD and TEM. It was concluded that,under the optimum reaction conditions of temperature 250℃,pressure 2.5 MPa,WHSV 2.0 h-1 and mole ratio of H2 to ethyl acetate 60,the average conversation of ethyl acetate and the average selectivity to ethanol reached 98.9% and 98.9% during the 1 000 h test,respectively.关键词
