  • Process for hydrogenating alkenes in the presence of alkanes and a heterogeneous catalyst
    Patent number: 5227552
    Abstract: The present invention provides a process for producing a selected paraffin from a reaction mixture containing(i) an acceptor olefin having the carbon backbone structure of said selected paraffin;(ii) a donor paraffin having a carbon backbone structure different from that of said selected paraffin;(iii) less than about 10 mole percent molecular hydrogen; which process comprises the steps of contacting said reaction mixture with a heterogeneous catalyst comprising active carbon in the absence of an added catalytic metal or metal compound to convert at least a portion of said acceptor olefin to said selected paraffin and to dehydrogenate at least a portion of said donor paraffin.
