Abstract
A catalyst for the selective hydrogenation of polyunsaturated hydrocarbons which contain entirely or predominantly more than five carbon atoms, containing palladium with a promotor on a metal oxide support. The promotor is a metal from the subgroup IB of the periodic system (preferably silver) and the metal oxide support (TiO.sub.2 optionally mixed with CeO.sub.2 and/or ZrO.sub.2) is macroporous, the pore volume being about 0.2 to 0.4, preferably about 0.25 to 0.30 ml per g of carrier and the proportion of the macropores having a diameter of more than 14 nm being at least 65%.
Claims22
A catalyst for the selective hydrogenation of polyunsaturated hydrocarbons having at least 5 carbon atoms comprised of salladium with a promoter on a metal oxide support, wherein the promoter is a metal from the subgroup 1B of the periodic table and wherein the metal oxide support is macroporous TiO.sub.2, the pore volume of the support being about 0.2 to about 0.4 ml per g of support and the proportion of the macropores having a diameter of more than 14nm being at least 65%.
