摘要：

Interactions between oxygen and metallic rhenium surface and Re Al2O3 catalysts have been investigated within the wide temperature range from 77 to 773°K in static and dynamic conditions. The contributions of reversible and irreversible oxygen sorption have been determined. Three temperature ranges of different oxygen-rhenium interactions have been distinguished: superficial (298-473°K), bulk oxidation (473-673°K), and above 673°K when ReO3 is formed. This paper discusses the conditions of carrying out oxygen chemisorption on rhenium catalysts in order to determine rhenium selective surface. © 1979.
