TL;DR: In this paper, a double-tubular membrane reactor equipped with a selective membrane tube as the inner tube was proposed, which makes it possible to obtain a product yield of a reversible reaction beyond its equilibrium value by continuous removal of the products during reaction.
Abstract: 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

TL;DR: In this article, a method for gas separation by permeation with one-side mixing is proposed and five types of stage flow patterns (one side mixing, countercurrent flow, cross flow, cocurrent flow, and perf...
