CATALYST FOR PRODUCING MONOCYCLIC AROMATIC HYDROCARBONS, AND METHOD FOR PRODUCING MONOCYCLIC AROMATIC HYDROCARBONS

摘要

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.
