A Process For The Manufacture Of Catalyst Support By In Situ Formation Of Shell Type Refractory Oxide On A Spherical Inert Inorganic Oxide Surface
Abstract: The present invention relates to a spherical catalyst support consisting of a thin annular shellof catalytically active material in gamma alumina formed in-situ on and bonded to a non-active inert core. The catalytic support is prepared by wetting an inert non-active core with colloidal aluminum sol, spraying a bohemite/pseudo bohemite powder along with a powder of water soluble polymer binder on said coloidal aluminum sol wetted inert core to form a coating thereon, neutralising the coated core, and calcining the coated core to convert the bohemite/pseudo bohemite into gamma alumina thereby forming a bond between the thin annular shell of preformed catalytically active material in gamma alumina and the inert, non-active core.
