LSU Doctoral Dissertations
Syngas produced by gasification of biomass or coal can be converted directly to ethanol and higher alcohols by processes based on heterogeneous catalysts. Ethanol can be used as a neat fuel or fuel additive or as a hydrogen carrier. Rhodium-based catalysts have been found to be most selective for the formation of C2 oxygenates from the hydrogenation of CO when suitably promoted. Here, we explore the effects of Mn, Fe, and Li promoters on Rh/TiO2. Rh-TiO2, Rh-Li/TiO2, Rh-Mn/TiO2, Rh-Mn-Li/TiO2 and Rh-Mn-Li-Fe/TiO2 catalysts were tested for the hydrogenation of CO …
