“…39 The unique ability of zeolites to adsorb water and release it upon heating has paved the way for the development of synthetic zeolites A, B, and X (Linde division of Union Carbide, 1940). 41 Subsequently, the scientific community has recognized the exceptional role of zeolites in shape-selective catalysis. Zeolites are crystalline microporous aluminosilicates, with pore sizes normally in the range of 0.3-2 nm.…”

“…In contrast with the extensive exploitation of mesostructured zeolitic materials in heterogeneous acid-type catalytic processes, their application as basic catalysts has attracted significantly less attention, especially for the transformation of renewable feedstock into valuable chemicals and fuels 5,[29][30][31][32] . In fact, there have been relatively few attempts aiming to produce basic microporous and mesoporous catalysts.…”

A combination of post-synthesis modifications and ion-exchange aiming to obtain basic cation-rich hierarchical zeolites X and Y was utilised in this work for the preparation of catalysts for biofuel production from vegetable oils. The secondary mesopore system with a narrow pore size distribution in the 4 nm range was introduced by successive acid and base treatments accompanied with surfactant templating. This was followed by ion-exchange with Cs + and K + cations to produce strong basic catalysts. The prepared hierarchical zeolites have been characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption, Fourier transform infrared spectroscopy (FTIR) and solid state NMR. The transesterification reaction over the zeolite catalysts was carried out in a microwave batch-type reactor and the effects of the reaction conditions, basic properties and pore structure of the hierarchical faujasites were studied in details. The conversion of triglycerides increased with increasing concentration of Cs and K in modified zeolites, but declined with decreasing framework aluminium content. The balance between the strength of the basic sites and their accessibility in hierarchical zeolites and its effect on the catalytic performance of these nanostructured materials is discussed.

“…Acidic zeolites have been shown to catalyze CÀ C bond forming alkylations due to Brønsted acid active sites, and well-defined porosity, the latter allowing for shape selectivity. [75][76][77][78][79] Among the investigated zeolites (HY, HZSM-5, and H-β), the HY zeolite was chosen as it displayed the highest activity. [80] The strength of the Brønsted acid sites was a critical factor that determined the alkylation products.…”
