Activated aluminum: Features of production and application in the synthesis of catalysts for pertochemistry and oil processing.

The best known procedures for aluminum activation are discussed and systematized. The analysis of published data and of results of the proper physicochemical research reveals that the phenomena of surface distribution, intergrain penetration and the internal diffusion in the crystal grains underlie the nature of aluminum activation with liquid metal alloys based on gallium. The experimental investigation using X-ray fluorescent spectroscopy of diffusion processes in the systems Al-Ga-In were performed for the first time. The procedures for formation of catalytically active complexes of AlCl3 type by treating the activated aluminum in situ in reaction media with chlorinated hydrocarbons were considered.
