| abstract |
The invention relates to a preparation method of a modified HZSM-5 molecular sieve catalyst for synthesizing durene, which comprises the steps of forming the HZSM-5 molecular sieve, surface acid modification, halogen element modification, metal modification and the like. Furthermore, the invention also relates to the catalysts produced by said process. The modified HZSM‑5 molecular sieve catalyst prepared according to the invention has higher selectivity to durene. |
