| 摘 要： | 以MgO为修饰剂对HZSM - 5沸石进行改性。以XRD、NH3-TPD为手段研究了 (MgO)HZSM - 5酸性并和甲苯甲醇烷基化反应的活性与选择性进行了关联。实验结果表明 ,MgO和HZSM - 5表面有一定的相互作用。HZSM - 5被MgO改性后 ,表面强酸中心减少从而使探针反应的活性下降但选择性提高。

| Abstract: | This paper studied the interaction of MgO with HZSM-5 by XRD and NH 3-TPD.The experimental results were related with the activity and selectivity of alkylation of toluene and methanol.It was shown that the activity of the reaction decreased,while the selectivity of producing p _xylene increased because MgO occupied the centers of acid of HZSM-5 zeolite surface. |

| Keywords: | HZSM-5 p -xylene selectivity interaction |
