“…[130][131][132] They include the separation of linear from branched hydrocarbons to enhance the yield and selectivity of hydroisomerization [133] and oligomerizaton. [134] Later in this Review, we highlight the performance of state-of-the art MFI membranes for the separation of xylene isomers and linear from branched hydrocarbons as a means for benchmarking the quality and separation capabilities of the current membrane technology, and to critically assess the potential for their implementation in the designs of membrane reactors.…”

Despite more than a decade of intense research on the high-resolution selectivity of thin zeolite films as alternatives to energy-intensive industrial separations, membranes consisting of intergrown, oriented zeolite crystals have fallen short of gaining wide commercial application. Factors including poor performance, high cost, and difficulties in scale up have contributed to this, and have also stunted their application in other niche markets. Until recently, rational design of these materials was limited because of the elusive mechanism of zeolite growth, and forced more empirical approaches. New understanding of zeolite growth along with recent advances in the molecular engineering of crystal microstructure and morphology, assembly of crystal monolayers, and synthesis of ordered films constitute a strong foundation for meeting stringent industrial demands in the future. Together with new processing capabilities, such a foundation should make it possible to synthesize commercially viable zeolite membranes through hierarchical approaches. Such advances open exciting prospects beyond the realm of separations for assembly of novel and complex functional materials including molecular sensors, mechanically stable dielectrics, and novel reaction-diffusion devices.

“…In this context, the removal of the intermediate products from the reaction before consecutive reactions could be also considered as an example of residence time control. The concept was demonstrated by Piera et al [229] based on zeolitic PBMRs in the oligomerization of i-butene, where MFI membranes packed with resin catalysts were used for the selective removal of the formed i-octene. In such a way, the formation of the undesired C 12 and C 16 hydrocarbons was decreased and at approximately 20 • C significant selectivity increase was obtained resulting in higher i-octene yields.…”

Literature on zeolite membranes in catalytic reactions is reviewed and categorized according to membrane location. From this perspective, the classification is as follows: (i) membranes spatially decoupled from the reaction zone; (ii) packed bed membrane reactors; (iii) catalytic membrane reactors and (iv) zeolite capsuled catalyst particles. Each of the resulting four chapters is subdivided by the kind of reactions performed. Over the whole sum of references, the advantage of zeolite membranes in catalytic reactions in terms of conversion, selectivity or yield is evident. Furthermore, zeolite membrane preparation, separation principles as well as basic considerations on membrane reactors are discussed.
