| titleOfInvention |
Selective preparation of para-xylene by toluene methylation (SELECTIVE PARAXYLENE PRODUCTION BY TOLUENE METHYLATION) |
| abstract |
The present invention selectively prepares para-xylene by reacting toluene with a methylating agent in the presence of a catalyst containing microporous material having a limiting dimension of about 1 to about 12, measured prior to the catalyst selectivity process, the catalyst The process of selectivity is carried out by the following steps (a) to (c): (a) pre-steaming the catalyst for at least about 10 minutes at a temperature of at least about 800 ° C .; (b) depositing about 1 to about 20 weight percent coke on the catalyst; And (c) continuously adjusting the coke weight percent on the catalyst to about 1 to about 20 weight percent. |
