Abstract

An aluminosilicate and a galloaluminosilicate of MFI structure are synthesized by the hydrothermal method from alkaline aluminosilicates. Structural, acidic, and catalytic properties of synthesized zeolites are investigated in the course of dehydrocyclization of lower alkanes. It is found out that aromatic hydrocarbons are formed in their highest amount when butane is converted over the galloaluminosilicate, while the lowest amount of them is resulted from the conversion of propane over the aluminosilicate. It is shown that to achieve the nigh conversion of propane and butane and the yield of desired product in the presence of the catalysts under study, the process temperature during the propane conversion should be 50 degrees higher under the same other reaction conditions
