FAU-to-MFI Interzeolite Transformations: Effects of Synthesis Conditions on Physicochemical Properties and Catalytic Performance

A series of experiments on interzeolite transformations of FAU into MFI was carried out. The study investigated the effects of various parameters, such as the chemical composition of parent zeolite, presence and type of seed crystals, and recrystallization method, on the physicochemical properties and catalytic performance of the MFI zeolites produced by interzeolite transformation from FAU. This enabled the researchers to optimize the transformation conditions and to propose highly efficient methods for targeted template-free synthesis of MFI zeolites with specific physicochemical properties and specific types of active sites. Based on a comprehensive analysis of the above-mentioned parameters governing the properties of target zeolites, a number of high-performance catalysts for methanol-to-hydrocarbon conversion were synthesized without templates, their catalytic performance being effectively controlled within a wide range.
