An improved catalyst for removal of acetylenes from liquid hydrocarbon streams with a minimum loss of diolefinic unsaturation present in said liquid composition is disclosed. The catalytic materials, basically copper metal associated with one or more activator metals are impregnated on a gamma alumina support prepared from an organo aluminum compound. The support has properties not found in alumina prepared from naturally occurring precursors.
