Method for preparing catalysts for heterogeneous catalysis by multiple-phase impregnation, catalysts and use of said catalysts

摘要

The invention concerns a method for so-called two-phase impregnation of a β-SiC support with high specific surface area, said method comprising at least the following steps: (a) a first impregnating at least once said support with a polar agent A, (b) a second impregnating which consists in impregnating at least once said support with at least an agent B less polar than agent A. Said method enables the production of novel catalysts for heterogeneous catalysis.
