提出了一种以选择性膜管为内管的双管膜反应器。这种反应器通过在反应过程中连续除去产物，可以获得可逆反应的产物产率超过其平衡值。采用微孔玻璃管作为选择性膜，气体透过几乎符合努森定律。以环己烷脱氢制苯为模型反应，在常压、453-493 K温度范围内，用膜反应器进行了实验研究。实验和理论表明，可以实现转化率比平衡时显著增加。
A membrane reactor, which is a double-tubular reactor equipped with a selective membrane tube as the inner tube, was proposed. Such a reactor makes it possible to obtain a product yield of a reversible reaction beyond its equilibrium value by continuous removal of the products during reaction. A microporous glass tube was employed as the selective membrane, through which gases permeate almost according to Knudsen''s law. Experiments in the dehydrogenation of cyclohexane to benzene as a model reaction were carried out, using the membrane reactor under atmospheric pressure in the range of 453-493 K. It was shown experimentally and theoretically that a marked increase in conversion over that at equilibrium can be achieved.
