    Abstract: The present disclosure relates generally to compositions and processes for modifying Fischer-Tropsch product selectivity. In particular, the disclosure provides for a for converting a mixture of hydrogen and carbon monoxide gases to a product composition comprising alcohols and liquid hydrocarbons via Fischer-Tropsch synthesis in the presence of a supported cobalt-manganese Fischer-Tropsch synthesis catalyst, the process comprising: contacting the catalyst with a first gaseous feed comprising carbon monoxide and hydrogen for at least 12 hours to provide via Fischer-Tropsch synthesis a first product composition comprising C5+ hydrocarbons and alcohol; then contacting the catalyst with a first selectivity gaseous composition comprising at least 35 vol % H2 and a H2:CO molar ratio of at least 2; and then contacting the catalyst with a second gaseous feed comprising carbon monoxide and hydrogen to provide a second product composition comprising C5+ hydrocarbons, with a selectivity of no more than 5% for alcohols. Optionally, the catalyst selectivity to alcohols can be reversed by contacting the catalyst with a second selectivity gaseous composition comprising CO or a H2:CO molar ratio of at below 1.5.

    Abstract: The present invention relates to a process for preparing ethers, particularly unsymmetrical ethers, and preferably ethers suitable for use as base stocks for lubricant compositions. In particular, the process involves the reaction of an α,β-unsaturated aldehyde with a trihydrocarbyl orthoester to form an α,β-unsaturated acetal and conversion of the α,β-unsaturated acetal to an ether through hydrogenation and hydrogenolysis.

    Abstract: 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.
