Iron Supported on a Carbon Material Prepared from Shadbush (Amelanchier) Wood Pulp: Carbidizing Bismuth-Promoted Fe-Containing Catalysts for the Hydrogenation of CO

Carbon material (CM) based on shadbush C Am ( Amelanchier ) wood pulp and a mixture of C Am + AMS, where AMS is aluminum magnesium spinel, are used as a support for a Fe-containing catalyst promoted by Bi (0.6 wt %) for the hydrogenation of CO.

Description
Summary:Carbon material (CM) based on shadbush C Am ( Amelanchier ) wood pulp and a mixture of C Am + AMS, where AMS is aluminum magnesium spinel, are used as a support for a Fe-containing catalyst promoted by Bi (0.6 wt %) for the hydrogenation of CO. The dynamics of the formation of iron carbides during the activation of iron oxides supported on the CM and CM–aluminum magnesium spinel mixture is studied, along with the effect bismuth has on this process. It is found that they already have nonzero magnetization at the stage of preparing the catalysts. It is shown that with Fe/C Am , only Hägg carbide forms in a medium of CO/H 2 (1 : 1), while a mixture of Hägg carbides and ε'-Fe 2.2 C forms when using Fe/(C Am + AMS). The promotion of the Fe/(C Am + AMS) catalyst by bismuth substantially increases the amount of formed Hägg carbide and affects the amount of ε'-Fe 2.2 C negligibly.
