摘要： The invention is directed to precipitating soluble nickel salts onto catalyst carriers by the addition of urea and reducing the insoluble nickel salt to the free metal to form catalyst-carrier compositions of high specific metal catalyst area wherein the amount of urea added satisfies the following equationU = f .sqroot.Ni (1)where:U = urea concentration in grams per liter;Ni = nickel ions concentration in grams per liter of water;f = a factor varying between 75/pH and 175/pH, in which pH = the pH value of the suspension of the silica in the water.
