Title:
METHOD FOR PRODUCING XYLENE
Document Type and Number:
WIPO Patent Application WO/2012/161263
Kind Code:
A1
Abstract:
This method for producing xylene involves producing xylene from an oil feedstock, which has a 10% distillation temperature of at least 135°C and a 90% distillation temperature of not more than 380°C, and comprises: a decomposition reforming reaction step in which a monocylic aromatic hydrocarbon is produced by bringing the oil feedstock into contact with a catalyst; a separation and recovery step in which a fraction A, which contains a monocyclic aromatic hydrocarbon with a 10% distillation temperature of at least 75°C and a 90% distillation temperature of not more than 140°C, a xylene fraction containing xylene, and a fraction B, which contains a monocyclic aromatic hydrocarbon with a 10% distillation temperature of at least 145°C and a 90% distillation temperature of not more than 215°C, are separated and recovered from the product produced in the decomposition reforming reaction step; and a xylene conversion step in which a mixed fraction that is obtained by mixing the fraction A and fraction B is converted to xylene by bringing the mixed fraction into contact with a catalyst containing a solid acid.
