A series of novel micro-mesoporous hydrocracking catalysts were prepared by using W-Ni supported on the different Y/Al-SBA-15 composites by impregnation method,and characterized by XRD,N2 sorption isotherms,FT-IR and SEM techniques.Their catalytic performances were evaluated by heavy oil hydrocracking reaction.The results showed that the catalysts possess both SBA-15 and Y structure and acidic property,which lead to a synergistic effect for heavy oil hydrocracking reaction.The properties and catalytic perfo...
