新型多孔质膜反应器的实验研究

A study on a new porous membrane reactor

为了使反应和分离更好地耦合,采用了催化剂分段填充的方法,将反应和分离由连续进行的过程改为分级进行,构造了一种离散型多孔质膜反应器结构(NPMR).以异丙醇脱氢生成丙酮为反应体系,在150～250℃的温度范围对这种结构进行了实验研究.结果表明,反应转化率比环隙内充满催化剂的传统多孔质膜反应器(CPMR)有了很大提高.在250℃、10 g催化剂、进料速率为2.4 mmol/min的实验条件下,产物中丙酮的摩尔分数可由78%提高到90%.

A study on a discrete new porous membrane reactor(NPMR), which can match better for reaction and separation process, adopts the method which is using catalysts to packed in the subsection area and changes the process of reaction and separation from synchronization to alternation. This proposed reactor was examined experimentally by using dehydrogenation of the IPA at the temperature(150250 ). The result showed that the conversion of the presented reactor was higher than that of the conventional porous membrane reactor (CPMR), in which the whole annular part was packed with the catalysts. The density of acetone in product increases from 78% to 90%, when the vacuum is 20.265 kPa, catalysts 10 g, feed velocity 2.4 mmol/min, and temperature (250 .)
