Studies on dealuminated mordenite catalysts. Some basic aspects of zeolite structure and chemistry are introduced. Subsequently, an industrially important representative of these porous aluminosilicates, viz. mordenite, is treated in more detail. Particular attention is paid to its dealuminated modifications. The most important techniques of zeolite dealumination are presented in a general way. The effect of dealumination on chemical and physical properties of mordenite is discussed, in particular the influence on Brßonsted and Lewis acidity, adsorption, and diffusion, these being the fundamental phenomena in the context of catalysis on mordenites. Catalytic behaviour of dealuminated mordenites is reviewed with respect to a series of basic reactions including cracking, hydrocracking, and isomerisation of paraffins, dealkylation and disproportionation of alkylbenzenes, as well as coke formation. Correlations between activity and/or selectivity and both chemical and structural properties of dealuminated mordenites are demonstrated.
