Abstract
The invention relates to a novel catalyst for the selective hydrogenation of unsaturated hydrocarbons. It is characterized in that the catalyst contains a group VIII metal deposited on a support previously modified by an element chosen from within group IIIA constituted by gallium and indium.
Claims18
A catalyst containing at least one group VIII metal and at least one group IIIA metal selected from the group consisting of gallium and indium, said metals being deposited on a catalyst support, said catalyst being produced by a process comprising:
- a) impregnating the support with a solution of a group IIIA compound precursor of said group IIIA metal, the metal concentration of the group IIIA compound precursor being chosen so that 0.01 to 10% of the group IIIA metal is fixed on the support,
- b) impregnating the product of (a) obtained with a solution of a group VIII compound precursor of said group VIII metal, the metal concentration of the group VIII compound precursor being chosen so that 0.01 to 10% of the group VIII metal is fixed on the support, and
- c) calcining the product of (b) at 110.degree. to 600.degree. C.
