Analyzing Structural and Physicochemical Characteristics of Bismuth-Promoted Fe-Containing Catalysts of CO Hydrogenation

Carbon material (СAm), prepared on the basis of shadbush (Amelanchier) wood is used as a support of bismuth-promoted (0.6 wt %) Fe-containing catalyst of CO hydrogenation. Structural, morphological, and physicochemical characteristics of the systems are studied. It is established via IR spectroscopy that sub-carbonyl and bridge forms of absorption are observed when bismuth is present on a surface of Fe/СAm during calcination in a stream of CO. At the same time, only iron oxide particles form, substantially facilitating the process of catalyst reduction afterward.
