Process for preparation of supports

摘要

Process for the preparation of a ceramic foam supporting one or more inorganic oxide(s) comprising impregnation of the foam with an impregnating phase comprising the inorganic oxide(s) precursor in an impregnating medium and drying wherein the impregnating phase has a viscosity greater than 1 cps at 20 DEG C, preferably of from 5 to 80 cps, more preferably of from 7 to 50 cps and wherein drying is performed without substantial prior draining of impregnating phase from the ceramic foam, and use of the ceramic foams of the invention as catalytic support in a catalytic conversion process.
