摘要：PtNi bimetallic and Ni monometallic catalysts supported on HY-Al2O3, HX-Al2O3, ZSM-5-Al2O3, USY-Al2O3, Beta-Al2O3 and Al2O3 were prepared and evaluated for the hydrogenation of maleic anhydride in the temperature range of 40-150 degrees C. Results from flow reactor studies showed that supports strongly affected the catalytic properties of different bimetallic and monometallic catalysts. The results showed that the HY-Al2O3 support exhibited the highest activity and selectivity. Using NiPt/Al2O3-HY catalyst and performing the reaction, it was possible to carry out the lowest reaction temperature ever carried at 100% conversion. Adding a small amount of Pt (0.5) to the Ni (5%)/Al2O3-HY catalyst that is effective for increasing the selectivity and activity. We also found that PtNi is an efficient catalyst for the one-pot conversion of maleic acid into succinic acid with 100% conversion at 40 degrees C.
