Title:
単環芳香族炭化水素の製造方法
Document Type and Number:
Japanese Patent JP5683342
Kind Code:
B2
Abstract:
A method for producing monocyclic aromatic hydrocarbons includes a cracking reforming reaction step of bringing an oil feedstock into contact with a catalyst for monocyclic aromatic hydrocarbon production containing a crystalline aluminosilicate, and causing the oil feedstock to react, thereby obtaining a product containing monocyclic aromatic hydrocarbons having 6 to 8 carbon atoms, a hydrogenation reaction step of hydrogenating a product produced in the cracking reforming reaction step, a monocyclic aromatic hydrocarbon recovery step of recovering monocyclic aromatic hydrocarbons having 6 to 8 carbon atoms separated from a hydrogenation product obtained in the hydrogenation reaction step and a recycling step of returning a heavy fraction having 9 or more carbon atoms separated from the hydrogenation product obtained in the hydrogenation reaction step to the cracking reforming reaction step.
