Carbon - process for producing the hydrogenation catalyst and the catalyst of the carbon unsaturated bond, and carbon using said catalyst - How hydrogenation of carbon unsaturated bond

摘要

PURPOSE: To obtain a catalyst enhanced in activity, selectivity, durability and filterability to a large extent and hydrogenating a carbon-carbon unsaturated bond in a high yield in a highly selective manner without generating environmental pollution due to chromium or the like. ;CONSTITUTION: A catalyst for hydropenating a carbon-carbon unsaturated bond is characterized by that at least one kind of a substance selected from a group consisting of oxides and hydroxides of aluminum, silicon, titanium, zirconium and magnesium, zeolite and silica-alumina is used as a carrier and an atomic ratio (the atomic ratio of the whole of the catalyst including a carrier in such a case that a substance containing an aluminum atom is used as the carrier)is Cu/Fe/Al/(alkali metal and/or alkaline earth metal)/Zn=1/0.4 to 2.5/0.5 to 5.0/0 to 0.4/0 to 1.0.;COPYRIGHT: (C)1993,JPO&Japio
