Abstract:

Single-tube membrane reactor has such disadvantages as difficulty in industrial scale-up，and low efficiency of coupling of reaction and separation. Discrete multi-tube membrane reactor has a compact structure with a larger heat transmission area as in tubular heat exchanger and realizes multi-stage separation as in plate column. In a test of sec-butyl alcohol dehydrogenation system at 150～225 ℃，mole fraction of methyl ethyl ketone reached 94%.

摘要：

由于单管程膜反应器不足主要表现在工业放大应用较困难，因此将多管程离散型膜反应器在单管程膜反应器基础上进行了改进，结构上吸取了列管式换热器结构紧凑的优点，操作上借鉴了板式塔多级分离的特点，可以在同一设备内完成多次的反应和分离，使反应和分离更好地耦合，从而弥补了单管程膜反应器的不足。本研究以仲丁醇脱氢为反应体系，150～225 ℃温度范围内进行试验，最终混合物中甲乙酮摩尔分数高达94%，结果表明反应器结构合理可行。
