REGENERATED HYDROCRACKING CATALYST AND METHOD FOR PRODUCING HYDROCARBON OIL

摘要

PROBLEM TO BE SOLVED: To provide a hydrocracking catalyst providing a high middle distillate yield in the stable period of the catalyst in the hydrocracking of a hydrocarbon raw material oil including a wax distillate for the purpose of producing the middle distillate and to provide a method for producing a hydrocarbon oil using the hydrocracking catalyst.

SOLUTION: This regenerated hydrocracking catalyst is formed by regenerating a used hydrocracking catalyst which contains both a carrier containing zeolite and an amorphous composite metal oxide having solid acidity, and at least one active metal selected from the noble metals of group 8 to group 10 of the periodic table and supported on the carrier; relative to the total mass of the catalyst, this regenerated hydrocracking catalyst contains 0.05-1 mass% of a carbonaceous material in terms of carbon atoms.
