Abstract: Zn aluminosilicates of a ZSM-5 zeolite structural type are synthesized from alkaline alumino-silica gels via hydrothermal crystallization. Structural and morphological data on the samples show that incorporating zinc into the zeolite structure leads to the formation of the particles of different morphology and elemental composition. Data from EDX analysis show that the distribution of elements throughout the zeolite catalyst is almost uniform, due to the morphology of the crystals that form. It is found that Zn aluminosilicates have high catalytic activity in the conversion of propane into aromatic hydrocarbons. A 0.81% Zn-AC sample exhibits the greatest selectivity toward aromatic compounds, due to the specific distribution and state of Zn in the zeolite and its acidic properties.
