TOLUENE METHYLATION PROCESS |
摘要 |
A method of preparing a xylene product is carried out by providing a reactor containing a non-steamed, phosphorus-treated ZSN-5-type zeolite catalyst. The catalyst is contacted with a toluene/methanol feed and a cofeed of hydrogen under reactor conditions suitable for the methylation of toluene. Water is introducing into the reactor during the methylation reaction under conditions that provide substantially no structural aluminum loss of die catalyst from such introduction of water. |
