ABSTRACT The development of hydrogenation processes for polyalphaolefin (PAO) lubricants, which hold commercialization potential, is a challenging endeavor. Here, we synthesized and characterized rod‐shaped γ‐alumina supported Pd catalyst PAO hydrofinishing, comparing it with Ni catalyst. Results indicated that Pd/Al 2 O 3 efficiently promoted whereas Ni‐based exhibited lower activity. Optimization reaction variables using the one‐factor‐at‐a‐time method revealed hydrogenated could be achieved 90% yield 5 wt.% catalyst, hydrogen pressure 12 bar, at 130°C after 7 h. superior performance fabricated catalysts, coupled use alumina suitable large‐scale reactors, suggests versatility process potential commercialization. Additionally, higher Pd/alumina compared to Ni/alumina was computationally assessed molecular level DFT methods.
