Abstract: 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.

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