Abstract
Novel alumina-supported nickel boride catalysts prepared by the borohydride promoted reduction of nickel arsenate are described. Method of catalyst preparation and process for hydrogenation of acetylenic and diolefinic compounds employing the invention catalysts are also described.
Claims15
A method for preparing a hydrogenation catalyst which comprises contacting an alumina-supported nickel arsenate with at least one borohydride compound;
- wherein said at least one borohydride compound conforms to the following formula:
- M(BH.sub.4).sub.n
- wherein M is a monovalent or divalent cation selected from the group consisting of:
- NR'.sub.4 ;
- wherein each R' is independently C.sub.1 through C.sub.10 alkyl, cycloalkyl, aryl aralkyl and alkaryl, alkali metals, and alkaline earth metals;
- wherein n=1 if M is a monovalent cation and n=2 if M is a divalent cation.
