- Abstract
- The physicochemical and catalytic properties of Mn-containing catalysts based on γ-AlO, obtained by various methods, were studied in the process of converting propane into olefin hydrocarbons. The dependence of the activity and selectivity of the catalytic systems on the localization of the introduced manganese and their acidic properties was shown. It was found that the greatest amount of olefin hydrocarbons during the conversion of propane is formed on the Mn-containing catalyst, into which manganese was introduced by the impregnation method. The nature and amount of carbon deposits formed on the studied catalysts during the propane conversion process were established. It was shown that the coke deposits formed on the Mn-containing catalysts have a virtually uniform structure and are characterized by a low degree of condensation, which allows for their relatively easy oxidative regeneration.
