amorphous alloys;  Ni-Zr-Al alloy;  catalysis;  Benzene hydrogenation: reaction kinetics

Ni23 3Zr6 7Al64Cu2 3Ce3.7 (atomic fraction) amorphous catalytic alloy was prepared by rapid solidification technology, activated by alkali washing and pumping Al, and a large specific surface area Ni-based amorphous alloy catalyst was prepared, and then its catalytic performance was tested on benzene hydrogenation. The results showed that the specific activity of this new catalytic material was 37.5% higher than that of conventional Raney Ni catalyst. The reaction kinetic analysis showed that the reaction sequence was basically one stage for hydrogen, and the reaction activation energy was about 31.2 kJ/mol, which was lower than that of conventional Raney Ni catalyst. Finally, the kinetic equation for benzene hydrogenation reaction is derived.
