| titleOfInvention | Method and apparatus for preparing p-xylene from methanol |
| abstract | The present invention discloses a method and an apparatus for preparing p-xylene from methanol. The method is mainly characterized in that first methanol feedstock produces a methanol aromatization reaction in a methanol aromatization reactor (2), and liquefied gas feedstock, a methanol aromatization gas product and non-aromatic raffinate oil separated from an aromatic hydrocarbon extraction apparatus produce a low-carbon hydrocarbon aromatization reaction in a low-carbon hydrocarbon aromatization reactor (6); second methanol feedstock as well as benzene and methylbenzene separated from an aromatic hydrocarbon rectifying tower (12) produce an alkylation reaction in an alkylation reactor (19), o-xylene, m-xylene and ethylbenzene separated from the aromatic hydrocarbon rectifying tower produce an isomerization reaction in an isomerization reactor (20), and fresh raw material benzene as well as C9 and aromatic hydrocarbons separated from the aromatic hydrocarbon rectifying tower produce a transalkylation reaction in a transalkylation reactor (21). P-xylene (13) separated from the aromatic hydrocarbon rectifying tower serves as a product. The present invention discloses the related apparatus. The method and the apparatus can produce p-xylene as much as possible. |
