Abstract

A mixed metal oxide catalyst for selective hydrogenation of dienes comprising a Group VIII metal, a trivalent metal, a Group IA metal, a Group IVB metal, a Group IIB metal, two Group VIB metals and SiO2—Al2O3 as balance. The catalyst comprises 10-40 wt % of Group VIII metal, 5-30 wt % of trivalent metal, 0.1-8 wt % of Group IA metal, 0.1-8 wt % of Group IVB metal, 0.1-30 wt % of Group IIB metal, 5-50 wt % of two Group VIB metals and 10-30 wt % of SiO2—Al2O3, based on the catalyst in terms of oxide, and has 150-300 m2/g of specific surface area, 0.4-0.8 ml/g of pore volume.
