Реферат:
Addition of tiny amount of noble metal to composition of Co-Al2O3 Fischer-Tropsch catalysts facilitates cobalt reduction and decreases the required activation temperature [1]. Noble metals may serve as sites for activation of hydrogen and also as nuclei for formation of metallic cobalt phase. Studying the reduction kinetics of noble metals Co-catalysts can help to understand the mechanism of the metallic cobalt particles formation and the role of noble metals in this process. Meanwhile the kinetic studies data on cobalt reduction are missing in literature. In present work the effect of ruthenium content on the process of the reductive activation of Ru-promoted Co-Al2O3 catalyst was investigated by thermogravimetric analysis (TGA) and by X-ray diffraction analysis in situ (XRD in situ ), we also studied the catalytic activity and selectivity of these catalysts in the Fischer-Tropsch synthesis (FTS).
