不难发现,对于任意一个反应速率和浓度成正相关的反应,(即反应级数大于0),CSTR的反应器体积是出口点+入口点和横轴纵轴构成的矩形,而PFR的反应器体积仅仅为该点之前的线下面积,在这种递增的图线下,出口点的线下面积总是小于这两点张成的矩形,因此CSTR的反应器体积总是要大于PFR,或者说PFR的反应器效率总是要大于CSTR...

As the yield increased, the residence time in PFR was less than that of CSTR and the immobilized cells were not hurt by the shearing. 随着转化率的提高,填充床反应器较连续机械搅拌反应器所需的停留时间短且不会因剪切力使固定化颗粒受到损伤。 www.chemyq.com 3. This is the website of the Inte...
I am trying to solve a CRE problem. a)CSTR followed by PFR in series. The volumes of both are given, the entering flow rate is given. The conversion of each reactor seperately is equal to .4. We are also give a table with conversion factors and corresponding reaction rates. The questio...
Combinations of Plug Flow Reactor (PFR) and continuous Perfectly Mixed Reactor (PMR, also known as Continuous Stirred Tank Reactor - CSTR) are widely known to give superior performance over a single reactor especially when multiple reactions take place in the reactor. The occurrence of a PMR in...
