Behaviors of NiW/Al-PILC catalysts in shale oil hydrogenation

NiW/Al-PILC catalyst was prepared using Al-PILC as the carrier, and its catalytic behaviors in hydrogenation of shale oil were investigated in comparison with NiW/γ-Al2O3. The catalysts were characterized, and （180 -350） ℃ diesel fractions from hydrogenation of shale oil over the catalysts analyzed. The results showed that behaviors of NiW/A1-PILC, with Al-PILC d（001） spacing of 1. 962 nm and surface area of 264.3 m^2·g^-1, were superior to those of NiW/γ-Al2O3. Diesel distillate was obtained from shale oil hydrogenation over NiW/AI-PILC with yield of 52.8%, kinematic, viscosity （20 ℃ ） of 5.025 mm^2 · s^-1, pour point of - 3℃, condensation point of 1 ℃, flash point of 84 ℃, cetane number of 64.3 and density -3 （20 ℃） of 0.8327 g＇cm
