| Abstract: | The influence of the zinc incorporation method (ion exchange, impregnation) and its content (from 0.25 to 0.75 wt %) in ZSM-5 zeolite on the physicochemical characteristics of the zeolite (textural parameters, concentration of acid sites) and on the catalytic activity of cracking catalysts with the additives containing the modified zeolites in transformations of hydrotreated vacuum gasoil was studied. The zinc introduction by impregnation leads to a slight decrease in the zeolite specific surface area and micropore volume from 420 to 380 m2/g and from 0.131 to 0.117 cm3/g, respectively, and the total concentration of acid sites at the maximal zinc content increases by 17% compared to unmodified ZSM-5. Modification of the zeolite samples with zinc by ion exchange does not alter the main pore structure parameters compared to the initial zeolite, whereas the acid site concentration reaches the highest values (up to 2025 μmol/g). With an increase in the zinc content of ZSM-5 zeolite, with both modification methods (ion exchange, impregnation), the yield of the gasoline fraction and aromatic hydrocarbons in liquid products of cracking of hydrotreated vacuum gasoil increases.
