Physicochemical and catalytic properties of Ga and In pentasils in the reaction of propane aromatization

Аннотация

Ga and In ZSM-5 zeolites are obtained via hydrothermal crystallization from alkali aluminosilicate gels. Their physicochemical and catalytic properties during conversion of propane into aromatic hydrocarbons are studied. These catalysts exhibit different activity and selectivity in propane aromatization process due to their specific physicochemical properties and the localization of promoter atoms in different sites of the zeolite structure. A zeolite containing 1.85 wt % of gallium oxide is the most effective catalyst for propane aromatization.
