In this review, it is demonstrated that zeolites have a potential to be used as crop protection agents. Similarly to kaolin, zeolites can be applied as particle films against pests and diseases. Their honeycomb framework, together with their carbon dioxide sorption capacity and their heat stress reduction capacity, makes them suitable as a leaf coating product. Furthermore, their water sorption capacity and their smaller particle sizes make them effective against fungal diseases and insect pests. Finally, these properties also ensure that zeolites can act as carriers of different active substances, which makes it possible to use zeolites for slow-release applications. Based on the literature, a general overview is provided of the different basic properties of zeolites as promising products in crop protection.

“…If we neglect axial and radial dispersion, three processes need to be balanced to obtain an optimal MR performance [17,35]. In terms of characteristic times these are: residence time, reaction time and a time related to hydrogen removal by the membrane.…”

“…[16]. Although zeolite membranes are also quite expensive [17], they could be more advantageous in terms of stability. However, the currently studied medium-pore zeolite MFI has pores larger than both isobutane and H 2 , which leads to only a modest separation factor.…”

“…With this development, the utilization of zeolite membranes was progressively investigated for catalytic reactions [21][22][23][24][25][26][27][28][29][30][31][32]. The special interest in membranes for catalysis science lies in the possibilities of equilibrium shifts, improved yields and selectivities as well as more compact operations compared to conventional processes.…”

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.
