| 摘 要： | 研究了碱金属Ｌｉ对氧化铝载体和ＭｇＯ对ＭｇＯ－ＳｉＯ２复合载体酸性的调变作用，通过实验得出了碱金属组分含量与载体酸量变化的关系。应用酸强度分布函数对载体酸性中心分布进行了定量表征。并用正态分布函数对酸性中心分布进行了拟合，得到了两个酸性参数。并将其与合成甲醇的反应性能进行了关联，甲醇收率和Ｃ２＋醇的比例与催化剂载体的酸性分布函数存在较好的对应关系，且由此确定了最佳酸强度值。获得的结果对催化剂设计具

| Abstract: | The adjustment effect of different alkali component on acid support has been studied. The distribution of acid sites on support has been quantitatively characterized with acid sites distribution function. Two acid parameters have been proposed, and they have been correlated with reactivity for methanol synthesis. The correlation results can be used to guide the catalyst designation. |
