Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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, wherein the amount of phosphorus supported on the medium pore size zeolite is within a range from 0.1 to 1.9% by mass based on the mass of the medium pore size zeolite. 2. The method according to claim 1 , wherein a cracked gas oil produced in a fluid catalytic cracking is used as the feedstock oil. 3. The method according to claim 1 , wherein the feedstock oil is brought into contact with the catalyst in a fluidized bed reactor. 4. The method according to claim 1 , wherein the medium pore size zeolite is a pentasil-type zeolite. 5. The method according to claim 1 , wherein the medium pore size zeolite is an MFI-type zeolite. 6. 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, wherein the amount of phosphorus is within a range from 0.1 to 5.0% by mass based on the mass of the catalyst. 7. The method according to claim 6 , wherein a cracked gas oil produced in a fluid catalytic cracking is used as the feedstock oil. 8. The method according to claim 6 , wherein the feedstock oil is brought into contact with the catalyst in a fluidized bed reactor. 9. The method according to claim 6 , wherein the medium pore size zeolite is a pentasil-type zeolite. 10. The method according to claim 6 , wherein the medium pore size zeolite is an MFI-type zeolite.
