着急请教一下：
1、 The plug flow conditions in the reactor were also maintained by avoiding back mixing and to minimize channeling. The conditions to avoid back mixing and channeling are (i) ratio of the internal diameter of the tube to the catalyst particle size (d/D p ) >10 and (ii) ratio of the catalyst bed to the catalyst particle size (L/D p ) >50。就是对于这段文字，它和载气的流速有关系吗？哪本书有详细说明 back mixing and channeling的呢？

2、就是现在自己的实验要控制产率在30%左右且需要稳定，然后把载气加到很大，结果还没有载气流速很小的时候稳定；更关键的问题是：在高的载气流速下，每次实验的重现性很差 ，就感觉载气太大了，这反应系统都紊乱了。希望能推荐点书，十分感谢。（大气压下，载气分压达到96千帕，反应物分压只有几千帕。） 返回小木虫查看更多
