  • Patent number: 11873270
    Abstract: The present disclosure relates to the technical field of catalysts, and specifically to a Zn—Al slurry catalyst, its preparation method and its application in preparing ethanol from syngas. The preparation method provided in the disclosure prepares the Zn—Al slurry catalyst by introducing a zinc component into an aluminum sol, and the preparation method has a simple operation and a lower cost. The Zn—Al slurry catalyst prepared in the disclosure includes the Zn component and the Al component, which may catalyze syngas to generate ethanol under mild conditions. Also, the catalyst has stable properties, is not easy to be deactivated, and reduces the cost of preparing ethanol from syngas. When the Zn—Al slurry catalyst provided in the disclosure is used as the catalyst for preparing ethanol from syngas, the reaction conditions are mild, and the syngas may be catalyzed to generate ethanol under the conditions of 250-340° C. and 3-5 MPa.

  • Patent number: 11117851
    Abstract: A reactor layout for a process of methanol production from low quality synthesis gas, in which relatively smaller adiabatic reactors can be operated more efficiently, some of the inherent disadvantages of adiabatic reactors for methanol production are avoided. This is done by controlling the outlet temperature in the pre-converter by rapid adjustment of the recycle gas, i.e. by manipulating the gas hourly space velocity in the pre-converter.

  • Patent number: 9533929
    Abstract: Sugars comprising the monosaccharides glucose and fructose, and the disaccharides sucrose and mannose are catalytically converted to ethanol at ambient temperature in a sulfate fortified acid medium in the presence of transition metal compounds possessing a degree of symmetry. This is not a fermentation process but is a catalytic chemical process where conversion efficiency is improved by saturating the acidic reaction mixture with inorganic sulfate salts to reduce competitive reactions. Ethanol formed during the reaction may be removed by distillation, following injection of nitric acid, facilitating a continuous process.

  • Publication number: 20090326080
    Abstract: A process for converting methanol to ethanol which comprises reacting methanol and carbon monoxide in the presence of a catalyst to produce a product comprising at least 25 mole % methyl acetate and, in some instances, acetic acid. The acetic acid then is reacted with at least one alcohol to produce at least one acetate selected from methyl acetate, ethyl acetate, and butyl acetate. The at least one acetate (if produced) and the methyl acetate produced as a result of reacting methanol and carbon monoxide then are hydrogenated to produce ethanol. Syngas may be produced from biomass to produce all or a portion of the methanol, hydrogen, and carbon monoxide requirements for the process.

  • Publication number: 20090018371
    Abstract: Methods and apparatus for producing alcohols from syngas are disclosed herein. In some variations, syngas is catalytically converted to methanol in a first reaction zone, and residual syngas from the first reaction zone is then catalytically converted to ethanol in a second reaction zone. Also, in some variations, syngas is catalytically converted to methanol in high yield in a first reaction zone, and the methanol is then converted (optionally, with additional syngas) to ethanol in a second reaction zone.
