    摘要： The present disclosure relates generally to processes for the Fischer-Tropsch production of hydrocarbons from methane. In particular, the disclosure provides for a process for the production of hydrocarbons and/or oxygenates, the process comprising: reforming a reforming feed comprising methane with water and/or oxygen to produce a reforming product stream comprising carbon monoxide and hydrogen; and contacting a hydrocarbon synthesis mixture comprising hydrogen and carbon monoxide with a Fischer-Tropsch hydrocarbon synthesis catalyst, wherein the hydrocarbon synthesis mixture comprises at least a portion of the reforming product stream to produce a hydrocarbon product stream with a selectivity for C5+ hydrocarbons of at least 50%, and/or a selectivity for oxygenates of at least 20%.

    摘要： The present invention provides a process for the hydrogenation of polyunsaturated hydrocarbon compounds, in particular di-olefins and alkynes, more particularly di-olefins, said process comprising contacting a feed comprising one or more polyunsaturated hydrocarbon compounds with a catalyst comprising copper and carbon in the presence of hydrogen, preferably wherein the catalyst is a copper catalyst on a carbon-containing support. The present invention also provides a process for producing a copper catalyst on a carbon-containing support and the use of a copper catalyst on a carbon-containing support to increase the selectivity towards di-olefin hydrogenation over mono-olefin hydrogenation in a process for hydrogenation of one or more di-olefins.

    摘要： A process for dehydrating methanol to dimethyl ether product in the presence of a catalyst and a promoter, wherein the catalyst is at least one aluminosilicate zeolite, wherein:—the aluminosilicate zeolite is selected from: (i) a zeolite having a 2-dimensional framework structure comprising at least one channel having a 10-membered ring, and having a maximum free sphere diameter of at least 4.8 Angstroms; (ii) a zeolite having a 3-dimensional framework structure comprising at least one channel having a 10-membered ring; or (iii) a zeolite comprising at least one channel having a 12-membered ring;—the promoter is selected from one or more compounds of Formula I: (I) wherein Y is selected from a C1-C4 hydrocarbyl substituent, and wherein each of X and any or all of the Z's may independently be selected from hydrogen, halide, a substituted or unsubstituted hydrocarbyl substituent, or a compound of the formula —CHO, —CO2R, —COR, or —OR, where R is hydrogen or a substituted or unsubstituted hydrocarbyl substituent, and wherein the molar ratio of promoter to methanol is maintained at less than 1.
