Physical Chemistry


The activity and selectivity of low-percentage (0.1–1 mass. %) Re-Al2O3 and Tc-Al2O3 catalysts in the dehydrogenation ofn-dodecane is shown to increase in response to an increase in the temperature of their activation in hydrogen from 500°C to 900°C. The activities of such catalysts are comparable to those of analogous alumina-platinum systems, while the selectivity of the former catalysts inn-monoolefin production is higher than that of the latter.
