ABSTRACT:
A feedstock comprising olefinic hydrocarbons having more than one double bond per molecule is selectively hydrogenated to produce hydrocarbons having less unsaturation relative to the feedstock by contacting the feedstock in the presence of steam and hydrogen with a catalyst comprising a Group VIII metal or an oxide thereof on a carrier comprising a Group II metal aluminate spinel containing tin or an oxide of tin. The feedstock can be produced by reforming paraffin and cycloparaffin hydrocarbons in the presence of steam with a catalyst comprising a Group VIII metal or an oxide thereof on a carrier comprising a Group II metal aluminate spinel containing tin or an oxide of tin.
