Pd Nanoparticles Immobilized on Boehmite as an Effi cient Heterogeneous Catalyst for Lubricant Hydrogenation
Abstract
To furnish high-quality poly-alpha-olefi n oils, hydro-fi nishing under mild reaction conditions by a novel heterogeneous
catalyst was accomplished. In this regard, Pd nanoparticles were immobilized on Boehmite. Then, the eff ect of hydrogenation
variables, i.e., catalytic loading, reaction pressure, and temperature on the catalytic effi ciency, was investigated with
response surface method. According to the results, a hydrogenation effi ciency of 85% was obtained at the optimum reaction
conditions of T = 130 °C, P = 8 bar, and catalyst dosage = 5 wt%. Notably, the catalyst was recyclable for four runs with
insignifi cant leaching of palladium nanoparticles. The comparison results suggested Pd/Boehmite catalyst as an appropriate
alternative to the commercial Pd/Alumina and Pd/Silica. Hot fi ltration test also approved heterogeneous nature of catalysis.
