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.
