摘要: 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 comprising 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 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, which greatly facilitates the conversion of carbon monoxide to methanol, while an extremely high activity of acetate hydrogenation is maintained.

摘要: The present invention provides a method for preparing methyl acetate, in which a feed gas containing an organic amine, dimethyl ether, carbon monoxide and optional hydrogen gas goes through a reactor loaded with a H-type mordenite catalyst, to produce methyl acetate; wherein said H-type mordenite catalyst is a H-type mordenite catalyst with adsorption of an organic amine. The method in the present invention improves the catalyst stability and prolongs the catalyst life, by using the H-type mordenite catalyst with adsorption of an organic amine as the catalyst and adding the organic amine in the feed gas to replenish the organic amine desorbed from the catalyst during the reaction.

摘要: Method for preparing methyl formate and coproducing dimethyl ether by reacting a formaldehyde and methanol raw material (molar ratio range of 1:4 to 1:0.05) in a First Reaction Region at ranges from 50° C. to 100° C. with Catalyst A resulting in post-reaction material separated into Constituent I. Reacting Constituent I in a Second Reaction Region at ranges from 50° C. to 200° C. and from 0.1 MPa to 10 MPa with Catalyst B resulting in post-reaction material, which is separated into methyl formate, dimethyl ether and Constituent II. At least 1% of dimethyl ether is product, and recycling the rest to the First Reaction Region. Constituent II is recycled to the Second Reaction Region. Each component is gaseous phase and/or liquid phase, independently. The method shows long catalyst life, mild reaction condition, high utilization ratio of raw materials, continuous production and large scale industrial application potential.
