    Abstract: 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.

    Abstract: The present disclosure relates generally to compositions and processes for producing Fischer-Tropsch catalysts. In particular, the disclosure provides for a process for producing a product composition comprising alcohols and liquid hydrocarbons via a Fischer-Tropsch synthesis reaction, the process comprising: contacting a mixture of hydrogen and a gaseous carbon oxide that is carbon monoxide, carbon dioxide or a combination thereof and an olefin co-feed with a supported cobalt-manganese Fischer-Tropsch synthesis catalyst to provide the product composition; wherein the olefin co-feed comprises at least one C2-C14 olefin and is present in an amount in the range of 0.001 wt % to 40 wt % relative to the total amount of hydrogen, the gaseous carbon oxide and olefin; wherein a weight ratio of manganese to cobalt in the catalyst is at least 0.05 on an elemental basis.
