【 摘 要 】

Galloalumosilicates having ZSM-5 structure are manufactured from the alkali alumina silica gels via the method of hydrothermal crystallization using different organic templating agents. Their physico-chemical and acidic properties are investigated and their catalytic reactivity is determined in the course of propane conversion into aromatic hydrocarbons. The highest catalytic reactivity and stability are exhibited by the Ga-containing zeolite synthesized using hexamethylenediamine as a structure-forming additive.
