Abstract
This invention discloses a method for producing ethanol and coproducing methanol on a catalyst in a reactor using a co-feed of a synthesis gas and acetate as a reaction raw material. More particularly, this invention provides a method for producing ethanol and coproducing methanol, characterized in that the method comprises the step of passing a raw material gas containing an acetate and a synthesis gas through a reactor loaded with a catalyst to produce ethanol and coproduce methanol under the conditions of a reaction temperature of 150-350?C, a reaction pressure of 0.1-20.0 MPa, a reaction volume hourly space velocity of 100-45000 mlg-1h-1, and an acetate weight hourly space velocity of 0.01-5.0 h-1; and the active components of the catalyst are copper and optionally zinc and/or aluminum. The method of this invention greatly facilitates the conversion of carbon monoxide to methanol, while an extremely high activity of acetate hydrogenation is maintained. Also, the method of this invention produces ethanol while a certain amount of methanol is coproduced, and the proportions of ethanol and methanol may be adjusted, which increases the flexibility of products.
