版主已经解释的很好。

one-pass conversion,或称single pass conversion,单程转化率,下面给出网上一英文解释,看是否适合。

As two or more chemicals (reactants) are passed through a reaction vessel they will react together immediately.

This usually has to do with continuous reactors and residency time.

Here is another example - component A and component B are added to a vessel, the vessel is stirred or heated (or both) and the end product is taken out of the vessel.

In some other chemical processes the different components are added to the vessel, taken from the vessel, re-added, retaken many times over. That is an example of a continuous reaction process. In a single pass conversion everything is added at once and the resulting product is removed once.

zhangwengui330: 这个没规定的,取决于你如何比对,这个概念只强调的是one-pass 2011-04-26 09:18:18

那么这个one pass conversion是指反应进行后稳定时的转化率么
