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

| Аннотация |
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 |
