Abstract
Supported nickel catalyst having high nickel loading and dispersion are manufactured using a dispersing agent. The dispersing agent molecules include at least one functional group that bonds with the nickel atoms and influences nanoparticle formation. The support material is loaded with at least about 5% nickel, more preferably at least about 8%, and most preferably at least about 12% by weight of the total catalyst. Catalysts manufactured using the organic dispersing agents and loaded with the foregoing amounts of nickel have metal dispersions greater than about 5% as measured by hydrogen adsorption, more preferably greater than about 10%, and most preferably greater than about 15%.
