在乙苯脱氢反应中利用钯膜反应器对氢的渗透作用使反应生成的氢不断从反应区移出，提高了乙苯脱氢转化率和苯乙烯生成选择性。在分离侧吹扫气中混入氧气，可以达到反应与分离、脱氢反应的吸热与氢的氧化反应放热的耦合，有利于使转化率和选择性的提高和能量的合理利用。对膜反应器的反应性能进行了研究。
In the ethylbenzene dehydrogenation reaction, the permeation of hydrogen from the palladium membrane reactor is utilized to continuously remove the hydrogen from the reaction zone, thereby increasing the dehydrogenation conversion of ethylbenzene and the selectivity of styrene generation. Mixing oxygen into the purge gas on the separation side can achieve the coupling between the reaction and separation, the endothermic dehydrogenation reaction and the exothermic oxidation reaction of hydrogen, which is beneficial to the improvement of conversion rate and selectivity and the rational utilization of energy. The reaction performance of membrane reactor was studied.
