A study was made on the duration of the single-pass lifespan of the gallium-containing catalyst in the course of conversion of a model mixture of C 1 -C 6 hydrocarbons into aromatic compounds. Using temperature-programmed desorption of ammonia, it has been found that some acid sites of the catalyst were irreversibly deactivated as a result of the reaction and oxidative regeneration. It has been shown that the gallium-containing catalyst characterized by high activity and stability in the course of aromatization of lower alkanes was able to withstand a certain number of reaction-regeneration cycles without reducing its activity.
