Studies on the promotion of nickel—alumina coprecipitated catalysts: II. Lanthanum oxide [PDF]
, 1988 Two series of lanthanum promoted nickel—alumina catalysts have been prepared by coprecipitation of the metal nitrates, using potassium carbonate. The molar ratio between nickel and the sum of aluminium and lanthanum was kept constant at 2.5 or 9.0 within
