“…During the alkylation of isobutane with olefins, the effects of the number of aluminum atoms in the zeolite lattice, the SiO 2 /Al 2 O 3 ratio, and the unit cell size on the activity indices of zeolite catalysts were studied. The yield of hydrocarbons was found to depend on the number of aluminum atoms in the crystal lattice of the catalyst [34,35]. In such cases, an increase in the number of silicon atoms associated with the number of aluminum atoms can increase the yield of C 8 target products.…”

This article provides an overview of zeolite-containing catalysts used in the alkylation of benzene and toluene with olefins, isobutane with butenes and butane-butene fractions, gasoline and oil fractions with olefins, propane-propylene, and butane-butylene fractions of catalytic cracking. Zeolites have various types of structures, including BEA, MFI, MWW, FAU, etc., which differ in pore size and the number and location of the channels. High-silica zeolites have a large pore volume, high acidity, good hydrothermal stability, and molecular sieve properties that provide high selectivity in alkylation processes.
