Abstract
Abstract A method for preparing a semi-homogeneous liquid suspension catalyst complex containing (1) an organometal compound, (2) at least one of nickel, iron, and cobalt, and (3) at least one of antimony, arsenic, or bismuth; and a process for the double bond isomerization, selective hydrogenation of a feedstock containing olefinic hydrocarbons having more than one double bond per molecule as well as trienes and acetylenes wherein said catalyst complex is utilized.
