“…The efficiency of isobutane alkylation with olefins on zeolite-containing catalysts depends on the reactions of hydride ion transfer and oligomerization [38]. A high yield of alkylate and a longer activity of the zeolite might be achieved by increasing the transfer rate of the hydride ion and the ratio of isobutane to olefin.…”

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.
