Abstract
The invention relates to a porous heterogeneous catalyst. In order to prepare a catalyst which catalyzes with a relatively high selectivity the hydrogenation of individual unsaturated bonds of polyunsaturated compounds it is proposed that the inner surface of the catalysts is coated with an ionic liquid.
Claims9
A porous heterogeneous catalyst comprising a preformed supported metal catalyst having a metal deposited on a carrier having an inner surface,
- wherein the inner surface of the catalyst is coated with an ionic liquid (IL) having an average thickness which is greater than or equal to the thickness of one ion layer of the IL and which is less than or equal to the thickness of ten ion layers of the IL, and
- wherein the metal is selected from the group consisting of nickel, cobalt, copper, iron, ruthenium, rhodium, iridium, palladium, and platinum.
