  • For further studied on nano-Ni catalytic hydrogenation of pyroole and its derivatives at normal temperature and pressure, we have did relevant catalytic hydrogenation experiments to pyrrole, pyrrolidine and pyrrolidone. The images and microstructure of nickel-based catalytic, hydrogenation activity and effect of ultrasonic wave were detected by the TEM-HREM and XRD. Besides the products of hydrogenation were investigated by the UV and GC. The results demonstrated that employment of ultrasonic wave has benefit on the maintenance of catalyst activity. The interspace of nickel (111) crystal face increases its distance at 1.5%. The nanosized nickel-based catalyst exhibits catalytic activity for the hydrogenation of pyrrole, pyrrolidine and pyrrolidone at normal temperature and pressure. The hydrogenation of pyrrole produces pyrrolidine at first, then the ring is broken and low-C hydrocarbons, ammonia etc are produced. The general reaction is found to be zero-order, which agrees with the character of surface-contact reaction.

An Investigation on Nano-Ni Catalytic Hydrogenation of Pyrrole and Its derivatives at Normal Temperature and Pressure

Abstract: For further studied on nano-Ni catalytic hydrogenation of pyroole and its derivatives at normal temperature and pressure, we have did relevant catalytic hydrogenation experiments to pyrrole, pyrrolidine and pyrrolidone. The images and microstructure of nickel-based catalytic, hydrogenation activity and effect of ultrasonic wave were detected by the TEM-HREM and XRD. Besides the products of hydrogenation were investigated by the UV and GC. The results demonstrated that employment of ultrasonic wave has benefit on the maintenance of catalyst activity. The interspace of nickel (111) crystal face increases its distance at 1.5%. The nanosized nickel-based catalyst exhibits catalytic activity for the hydrogenation of pyrrole, pyrrolidine and pyrrolidone at normal temperature and pressure. The hydrogenation of pyrrole produces pyrrolidine at first, then the ring is broken and low-C hydrocarbons, ammonia etc are produced. The general reaction is found to be zero-order, which agrees with the character of surface-contact reaction.
