Reduction kinetics of benzylideneaniline over Pd/SiO2−AlPO4 and Pd/sepiolite catalysts

The liquid-phase hydrogenation of benzylideneaniline over various Pd catalysts, using gaseous hydrogen has been studied. We have synthesized several Pd catalysts (3 wt.%) over SiO2−AlPO4 and sepiolite supports, and determined their metal surface area by X-ray diffraction. The study performed shows that the process follows a Langmuir-Hinshelwood kinetics with zero order in benzylideneaniline, ri=kokPH2 (1+KPH2)−1.
