| titleOfInvention | Production method of xylene |
| abstract | The invention relates to a method for producing xylene, and mainly solves the problems of low conversion rate of toluene, low para-selectivity and low utilization rate of methyl groups in the prior art. The present invention adopts the production method of xylene, which includes reacting raw materials for gas phase reaction in the presence of a catalyst to generate xylene, and the raw materials for the reaction include aromatic hydrocarbons and methylating reagents; wherein the aromatic hydrocarbons are obtained from benzene and/or toluene, and the The technical solution that the catalyst contains ZSM-22/ZSM-23 co-produced molecular sieve and/or ZSM-22/ZSM-5 co-produced molecular sieve can better solve this problem and can be used in the industrial production of xylene. |
