Metal-carbon nanostructured membrane catalysts

Abstract

The membrane catalysts possess a selective permeability for one of the reagents. The carbon materials got the increasing value in processes of membrane for gas separation due to their high selectivity and permeability, high hydrophobicity and stability in corrosive and high-temperature operations. At the same time carbon materials are widely known supports of metal catalysts. The present work is the first sample of development of the methods of preparation of carbon membrane catalysts with metal nanoparticles in a carbon membrane matrix. The other granulated rhenium-carbon catalyst was obtained for the first time by high-temperature destruction of copolymers. It is shown, that both catalysts are active in hydrocarbons dehydrogenation and demand considerably the smaller maintenance of metal, than the traditional catalysts put on coal, with other things being equal. © 2007 Springer.
