Abstract

The influence of the introduction of alkaline promoters into chromium oxide catalysts for the dehydrogenation of propane in the presence of CO2 was investigated. The positive role of potassium, which manifested itself in an increase in the selectivity and stability of catalysts, was shown. It was established by IR spectroscopy that, in the chromium oxide catalysts where a substantial part of protons is replaced by an alkaline ion, a decrease in their activity and stability in the dehydrogenation of propane in the presence of CO2 was observed.
