| Abstract: | Superhigh-silica ZSM-type zeolites with silica moduli of 100–220 were synthesized using hexamethylenediamine as a structure-forming additive. Physicochemical methods were used to identify them as ZSM-5-type zeolites, determine their degree of crystallinity, specific surface areas, and morphology of crystals, and study the phase and elemental composition. The strength and concentration of acid centers were found to decrease as the silica modulus grew. The zeolites obtained can be used as the main component of catalysts for refining low-octane gasoline fractions and methanol conversion into hydrocarbons. |
