Dealkylation and transalkylation of heavy aromatic hydrocarbons |
| abstract |
Contacting method of the present invention C 9+ A method for producing xylenes from aromatic hydrocarbons, C 9+ the first feedstock with a first catalyst comprising an aromatic hydrocarbon under effective vapor phase dealkylation conditions in the presence of hydrogen, C Dealkylating a portion of the 9+ aromatic hydrocarbons and producing a first product comprising benzene and unreacted C 9+ aromatic hydrocarbons. A second feedstock comprising toluene is contacted with a second catalyst under effective gaseous toluene disproportionation conditions in the presence of hydrogen to disproportionate at least a portion of the toluene and produce a second product comprising paraxylene. A third feedstock comprising C 9+ aromatic hydrocarbons and benzene and/or toluene is contacted with a third catalyst under effective liquid C 9+ transalkylation conditions in the presence of hydrogen to transalkylate at least a portion of the C 9+ aromatic hydrocarbons. And a third product comprising xylene is produced. |
