Method for producing monocyclic aromatic hydrocarbons |
摘要 |
A method 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 a 90 volume % distillation temperature of not more than 380° C., the method including: a cracking and reforming reaction step of obtaining a product containing monocyclic aromatic hydrocarbons of 6 to 8 carbon number from the feedstock oil, a refining and collection step of refining and collecting monocyclic aromatic hydrocarbons of 6 to 8 carbon number that have been separated from the product, a hydrogenation reaction step of hydrogenating a heavy fraction of 9 or more carbon number separated from the product, and a recycling step of returning the heavy fraction hydrogenation reaction product obtained in the hydrogenation reaction step to the cracking and reforming reaction step. |

1. A method 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 a 90 volume % distillation temperature of not more than 380° C., the method comprising:
a cracking and reforming reaction step of bringing the feedstock oil into contact with a monocyclic aromatic hydrocarbon production catalyst comprising a crystalline aluminosilicate, and reacting the feedstock oil to obtain a product comprising monocyclic aromatic hydrocarbons of 6 to 8 carbon number, a refining and collection step of refining and collecting monocyclic aromatic hydrocarbons of 6 to 8 carbon number that have been separated from the product obtained in the cracking and reforming reaction step, a hydrogenation reaction step of hydrogenating a heavy fraction of 9 or more carbon number separated from the product obtained in the cracking and reforming reaction step, and a recycling step of returning a heavy fraction hydrogenation reaction product obtained in the hydrogenation reaction step to the cracking and reforming reaction step. |
