NICKEL UPON TRANSITION ALUMINA CATALYSTS

摘要

The invention provides new catalysts, useful for various hydrogenation reactions, which consist of 5 to 40% (w/w) of nickel upon a transition alumina, in particular gamma alumina support. These catalysts have an active nickel surface area of between 80 and 300, preferably 100-250 m2/g of nickel and the nickel crystallites have an average diameter of 1 to 5, preferably 1.5 to 3 nanometers. The nickel crystallites are dispersed for at least 95% in the pores of the alumina.
