A catalyst for producing monocyclic aromatic hydrocarbons of 6 to 8 carbon number from a feedstock oil having a 10 volume % distillation temperature of at least 140° C. and an end point temperature of not more than 400° C., or a feedstock oil having a 10 volume % distillation temperature of at least 140° C. and a 90 volume % distillation temperature of not more than 360° C., wherein the catalyst contains a crystalline aluminosilicate, gallium and/or zinc, and phosphorus, and the amount of phosphorus supported on the crystalline aluminosilicate is within a range from 0.1 to 1.9% by mass based on the mass of the crystalline aluminosilicate; and a method for producing monocyclic aromatic hydrocarbons, the method involving bringing a feedstock oil having a 10 volume % distillation temperature of at least 140° C. and an end point temperature of not more than 400° C., or a feedstock oil having a 10 volume % distillation temperature of at least 140° C. and a 90 volume % distillation temperature of not more than 360° C., into contact with the above-mentioned catalyst for producing monocyclic aromatic hydrocarbons.
A method for producing monocyclic aromatic hydrocarbons of 6 to 8 carbon number, the method comprising bringing a feedstock oil containing polycyclic aromatic hydrocarbons and having a 10 volume % distillation temperature of at least 140° C. and an end point temperature of not more than 400° C., or a feedstock oil containing polycyclic aromatic hydrocarbons and having a 10 volume % distillation temperature of at least 140° C. and a 90 volume % distillation temperature of not more than 360° C., into contact with a catalyst comprising a medium pore size zeolite, gallium and/or zinc, and phosphorus,
