Abstract:
1. An adsorption composition comprising oxides of copper, zinc and aluminum, wherein copper is present in a copper-comprising fraction selected from the group consisting of metallic copper, Cu wherein the adsorption composition comprises copper in an amount, calculated as CuO, of from 10% by weight to 70% by weight based on the total amount of the adsorption composition; wherein the adsorption composition comprises zinc in an amount, calculated as ZnO, of from 10% by weight to 70% by weight based on the total amount of the adsorption composition; wherein the adsorption composition comprises aluminum in an amount, calculated as Al wherein the copper-comprising fraction has a degree of reduction, expressed as weight ratio of metallic copper to the sum of metallic copper, Cu wherein the adsorption composition comprises no zirconium dioxide except for unavoidable impurities.
