| 1. A process for selectively removing alkynes or diolefins from a feedstock also containing olefins, the process comprising
contacting the feedstock with hydrogen in the presence of a catalyst composition made by the method comprising:
(a) applying a rhodium compound to a support;
(b) applying an indium compound to the support; and
(c) applying a further metal compound selected from the group consisting of at least one of iron, cobalt, and ruthenium compounds
to the support; and
(d) hydrogenating the alkynes or diolefins in the feedstock with high selectivity to olefins and low selectivity to oligomers
and saturates.
