Abstract

Combined techniques of XRD, SQUID magnetometry, and electron magnetic resonance spectroscopy were employed to determine the different phases (Co, CoO, Co₃O₄) and electronic states (CoO, Co²⁺, Co³⁺), and their concentrations in cobalt catalysts supported on high surface area xerogel, aerogel, SiO₂ and Al₂O₃. These results were then compared with the yields and distribution of products in conventional gas-phase and supercritical-phase Fischer-Tropsch synthesis. Correlations between the different electronic states of cobalt and product yields were discussed. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
