The aim of present work was to study the influence of SiO2/Al2O3 molar ratio (MR) on nickel behavior in the mordenites with wide variation of MR during reduction in hydrogen flow. It was found that during reduction treatment variation of MR in mordenite from 10 to 206 influences reducibility and mobility of reduced nickel species. Stability of the reduced samples during storage in air at ambient conditions also depends on molar ratio. Variation of MR of mordenite does not change crystal structure, but results in different ionic properties. This effect is explained by variation of acidity of zeolite matrix in line with variation of chemical composition.
