An oil sludge was hydroconverted to clean jet and diesel fuels over Ni 10% /MPYZ under 5 MPa of initial hydrogen pressure (IHP) at 160 °C and the high yields of branched alkanes (25.5 wt%) and cycloalkanes (21.1 wt%) were obtained. • OS was quickly extracted with a mixed solvent to afford EP OS in the yield of 90.6%. • Ni/MPYZ effectively catalyzed the formation of H+ and H⋯H from H 2. • Ni/MPYZ is highly active for saturating ARs in EP OS and removing HAs from EP OS. A mesoporous Y zeolite (MPYZ)-supported nickel catalyst (Ni/MPYZ with 10% of Ni loading) was prepared by modifying deposition-precipitation (MDP) to uniformly disperse Ni nanoparticles (NNPs) onto MPYZ. An oil sludge (OS) was exhaustively extracted with isometric carbon disulfide and acetone mixed solvent to obtained the extractable portion (EP OS) in the yield of 90.6%. EP OS was subjected to the catalytic hydroconversion (CHC) over Ni 10% /MPYZ at 160 °C under 5 MPa of initial hydrogen pressure (IHP) for 18 h in n -hexane to afford catalytically hydroconverted EP (EP CHC). The results show that alkenes, aromatics, and heteroatom-containing compounds (HACCs, some of which are also aromatics) in EP OS were completely converted to chain alkanes and cyclanes. Ni/MPYZ can effectively activate H 2 to biatomic active hydrogen (H⋯H) and heterogeneously split H 2 to relatively mobile H+ and immobile H− attached on the surface of Ni/MPYZ. The transfer of H⋯H and H+ to EP OS plays crucial roles in the CHC of EP OS. Such mechanisms are evidenced by the CHC of benzyloxybenzene over Ni/MPYZ. Ni 10% /MPYZ maintained high activity for the CHC after 5 repeated cycles. [ABSTRACT FROM AUTHOR] |
