The effects of rare earths on supported amorphous NiB/Al2O3 catalysts Original Research Article

The technique of pulse microreaction was applied to study the effects of rare earths on the catalytic properties of supported amorphous NiB/Al2O3 catalyst for benzene hydrogenation. The characteristics of catalysts are investigated by using ICP, XRD, TPR, TPD, DSC and H2 chemisorption. Experimental results show that rare earth addition is helpful for the reduction of nickel oxide, makes the nickel particles smaller and increases the surface area of active nickel.
