Method for Selecting a Catalyst for the Production of Paraxylene by Methylation of Benzene and / or Toluene |
| abstract |
Contacting an aromatic hydrocarbon feedstock comprising benzene and / or toluene with an alkylating reagent comprising methanol and / or dimethyl ether in an alkylation reaction zone under alkylation conditions in the presence of an alkylation catalyst to form an alkylated aromatic product comprising xylene ≪ / RTI > is produced. The alkylation catalyst comprises a molecular sieve having a constraint index of < RTI ID = 0.0 > 5, < / RTI > By using a molar ratio of at least 1: 4 alkylating agent: aromatic, the alkylation catalyst can be selected to produce more than equilibrium para-xylene. |
