A method for co-production of mesitylene and xylene based on the upgrading of C9+ heavy aromatics |
| abstract |
The invention provides a method for co-producing mesitylene and xylene based on the upgrading of C9+ heavy aromatic hydrocarbons. reaction to obtain a reaction product; fractional distillation is performed on the reaction product to obtain a light fraction containing xylene and a heavy fraction containing mesitylene respectively; wherein, the catalyst is prepared according to a preparation process comprising the following steps: the molecular sieve is subjected to alkali treatment and The modified molecular sieve is obtained by acid treatment; the modified molecular sieve is compounded with alumina to form a composite carrier; the composite carrier is metal-modified to obtain a catalyst. The invention uses C9+ heavy aromatic hydrocarbons as raw materials, realizes co-production of mesitylene and xylene, and can improve the yield of target products. |
