用催化反应速度表示的活性,对不同催化剂并无对照意义。即使在一定溫度下,同一表面的各区活性也是不同的。所以反应速度数值沒有任何理論的意义。为了闡明催化活性,通常可用经驗关系式計算及对照。催化活性的經驗关系式可分为二大类:第一类为研究給定反应在不同催化剂上的作用,其中某些参数 The activity expressed by the catalytic reaction rate has no contrast to different catalysts. Even at a certain temperature, the activities of the same surface area is different. Therefore, there is no theoretical value of the reaction rate. In order to clarify the catalytic activity, empirical correlation can usually be used to calculate and control. The empirical relationship of catalytic activity can be divided into two broad categories: The first is to study the effect of a given reaction on different catalysts, some of which
