Аннотация: The diffuse-reflectance IR spectroscopic data using acetylene as a probe molecule showed the strengthening of basic properties of γ-Al2O3 modified with alkali metals in the sequence Al2O3 < Na/Al2O3 < K/Al2O3 < Rb/Al2O3 < Cs/Al2O3. The increase in the basicity of the support of Pd–alumina catalysts had a positive effect on the ethene selectivity in hydrogenation of acetylene in an ethane–ethene mixture.

Ключевые слова: acetylene, ethene, hydrogenation, palladium, modification of the support, diffuse reflectance FTIR spectroscopy, DRIFT, acid–base properties.
