Hydrocracking catalyst and hydrocracking method for hydrocarbon oils

摘要

A hydrocracking catalyst for hydrocarbon oil, comprising a complex oxide with at least 2 different elements selected from Group 3b, Group 4a, Group 4b and Group 5b of the Periodic Table, zeolite having a solid Al-NMR spectrum wherein the ratio A/B of the peak area A in a chemical shift of -30 to 18 ppm to the peak area B in a chemical shift of 20-100 ppm is 0.01-0.39 and whose surface area of pores of diameter 10 angstrom or smaller constitutes 10-85% of the total surface area, and at least one metal selected from Group 6a and Group 8 of the Periodic Table. Also, a hydrocracking method characterized by hydrocracking of petroleum distillates with a boiling point of 250-600 DEG C. using the hydrocracking catalyst in the presence of hydrogen, under conditions with a reaction temperature of 100-800 DEG C., a reaction pressure of 3-30 MPa, an LHSV of 0.01-10 h-1 and a hydrogen/oil ratio of 100-2500 Nm3/m3.
