  • Patent number: 11603342
    Abstract: The invention provides a process for producing methanol, which process comprises contacting H2 and CO2 with a solid catalyst, at a temperature of from 200° C. to 300° C. and at a reactant pressure of from 150 bar to 500 bar, which reactant pressure is the sum of the partial pressures of the H2 and the CO2, wherein: the molar ratio of the H2 to the CO2 is x:1.0, wherein x is from 2.5 to 3.5; and the catalyst comprises: (i) a copper component which is Cu, CuO or Cu2O, or a mixture of two or three thereof, and (ii) ZnO, wherein the catalyst has a specific copper surface area of at least 10 m2/g-catalyst.
    Type: Grant

  • Patent number: 9133084
    Abstract: A process for the preparation of methanol having the process a carbon oxides per-pass conversion equal to or higher than 65%, and a selectivity to methanol formation equal to or higher than 75% by submitting carbon dioxide, carbon monoxide or a mixture of carbon monoxide and carbon dioxide to a hydrogenation reaction using a specific metal compound and specific reaction conditions of temperature, pressure, space velocity and a specific range of molar ratio of hydrogen to carbon dioxide, of hydrogen to carbon monoxide, or of hydrogen to the mixture of carbon monoxide and carbon dioxide. It further relates to a process for converting the methanol obtained into dimethyl ether or into a mixture of (C2-C8)alkene and (C1-C8)alkane.
