摘要
用Ｍｇ、Ｚｎ、Ｆｅ对ＨＺＳＭ－５沸石催化剂改质处理，在恒温条件下测定其α值，探讨催化剂的初活性随金属载量的变化关系。在该试验条件下，催化剂的活性随金属载量的增加而下降；对于同一种催化剂，相同的金属载量，用Ｚｎ改质的催化剂活性最高，Ｍｇ次之，Ｆｅ最低。
The relation is investigated between the initial activation of catalyst and the content ofmetal by medifying the HZSM-5 zeolite with magnesium, zinc and iron and measuring theirα values at constant temperature. At the test condition the activation of catalyst decreaseswith the increase in the metal content.For each catalyst with same metal content,the acti-vation of catalyst modified by zinc is the highest,that by magnesium is lower and that byiron is the lowest.
