Bibliographic description in the original language

Boretskaya A. V. Modification of a phase-inhomogeneous alumina support of a palladium catalyst. Part I: effect of the amorphous phase on the textural and acidic characteristics of alumina and methods for controlling its phase homogeneity / A.Boretskaya, I.Il'yasov, S.Egorova, A.Popov, A.Lamberov // Materials Today Chemistry – 2020. - Vol.18 – 100371 (doi.org/10.1016/j.mtchem.2020.100371) Q2

Annotation

It was shown for the first time that amorphous phase in an alumina support promotes the formation of palladium particles in a wide size range. This catalyst has a low selectivity to butenes in the 1,3-butadiene hydrogenation. It was suggested that surface palladium aluminates contribute to an increase in butene selectivity up to 99.5% at a hydrogenation temperature of not more than 65 C. At higher reaction temperatures, the catalyst based on phase-homogeneous g-Al2O3 has the highest activity and butene selectivity. This catalyst was obtained by the traditional impregnation method and contains highly dispersed palladium particles with a sufficiently high electron density. It was shown that the formation of hydride forms on palladium particles with a size of less than 1 nm was detected by temperature-programmed reduction with hydrogen
