A carrier complex and a hydrotreating catalyst containing acidic amorphous silica-alumina, in particular a hydrocracking catalyst containing acidic amorphous silica-alumina in combination with a modified zeolite-Y, treats petroleum hydrocarbon materials to produce middle distillates. The amorphous silica-alumina has a SiO2 content of 10-50 wt. %, a specific surface area of 300-600 m2 /g, a pore volume of 0.8-1.5 ml/g and an IR acidity of 0.25-0.60 mmol/g. The catalyst shows a relatively high activity and mid-distillate selectivity and can be particularly used in hydrocracking process for producing mid-distillates with a higher yield.Field of SearchZeoliteAnd Group VIII (Iron Group or Platinum Group) metal containing And Group III or rare earth metal (Al, Ga, In, Tl, Sc, Y) or Lanthanide containing And Group VIII (Iron Group or Platinum Group) containing Faujasite type (e.g., X or Y, etc.) Support per se And Group IV metal containing (i.e., Ti, Zr, Hf, Ge, Sn or Pb) Titanium containing And Group VIII metal containing (i.e., iron or platinum group) Iron group metal and Group III metal containing (i.e., Fe, Co or Ni and Sc, Y, Al, Ga, In or Tl) Nickel containing Iron containing Of chromium And Group III metal containing (i.e., Sc, Y, Al, Ga, In or Tl) Of molybdenum And Group III metal containing (i.e., Sc, Y, Al, Ga, In or Tl) And Group III metal containing (i.e., Sc, Y, Al, Ga, In or Tl) And Group III metal containing (i.e., Sc, Y, Al, Ga, In or Tl) And Group II metal containing (i.e., alkaline earth, Be, Mg, Zn, Cd or Hg) Zinc containing With group III metal, rare earth metal, or metal oxide (i.e., Sc, Y, Al, Ga, ln, Tl, metal of atomic number 57-71, or oxide thereof) With group IV metal or metal oxide (i.e., Ti, Zr, Hf, Ge, Sn, Pb, or oxide thereof) With group II metal or metal oxide (i.e., alkaline earth metal, Be, Mg, Zn, Cd, Hg, or oxide thereof) With group VIII metal or metal oxide (i.e., iron, or platinum group metal, or oxide thereof) Metal or metal oxide catalyst With group III metal, rare earth metal, or metal oxide (i.e., Sc, Y, Al, Ga, In, Tl, metal of atomic number 57-71 or oxide thereof) With group IV metal or metal oxide (i.e., Ti, Zr, Hf, Ge, Sn, Pb, or oxide thereof) With group II metal or metal oxide (i.e., alkaline earth metal, Be, Mg, Zn, Cd, Hg, or oxide thereof) With group VI metal or metal oxide (i.e., Cr, Mo, W, Po, or oxide thereof) With group VIII metal or metal oxide (i.e., iron or platinum group metal, or oxide thereof) Metal or metal oxide containing catalyst |
