Abstract

CARDENAS, Agobardo; ACERO, Fabio N  and  DIAZ, José de J. CHROMIUM OXIDE OVER ACTIVATED CARBONS AS CATALYST FOR OXIDATIVE DEHYDROGENATION OF ISOBUTANE. Rev.Colomb.Quim. [online]. 2007, vol.36, n.1, pp.93-108. ISSN 0120-2804.

The functional groups at the surface of an activated carbon Norit ROX 0.8^® were modified through reaction with nitric acid, 8.8% O₂ in N₂ and H₂ . The modified carbons were impregnated with a CrO₃ aqueous solution and used in the Oxidative Dehydrogenation of isobutane to isobutene (ODH). The formation of isobutene was observed at 443 K, with a maximum selectivity of 85% and a yield of 9%.

Keywords : Activated Carbon; Oxidative Dehydrogenation; Isobutane; Thermal Programmed Desorption.
