| titleOfInvention | Method for preparing ethanol through acetic ester hydrogenation |
| abstract | The invention relates to a method for preparing ethanol through acetic ester hydrogenation. The method performs an acetic ester hydrogenation reaction to generate ethanol under the conditions of certain temperature, pressure, hydrogen/ester molar ratio and hydrogen circulation in a fixed-bed reactor filled with a copper-based catalyst, wherein in the copper-based catalyst, a mesoporous molecular sieve MCM-41 is used as a carrier, copper is used as an active component, and the oxide of at least one element of La and Ce is used as an auxiliary; and the MCM-41 accounts for 40-90% of the catalyst by weight, the active component copper accounts for 10-50% of the catalyst by weight, and the auxiliary accounts for 0.1-20% of the catalyst by weight. According to the method for preparing ethanol through acetic ester hydrogenation, provided by the invention, when the reaction temperature is 220 DEG C, the reaction pressure is 3MPa, the hydrogen/ester molar ratio is 30 and the mass airspeed of acetic ester is 2h<-1>, the conversion rate of acetic ester is 98.5%, and the ethanol selectivity is as high as 99.6%, thereby showing extremely high hydrogenation activity, selectivity and stability. |
