The invention concerns a method for so-called two-phase impregnation of a .beta.-SiC support with high specific surface area, said method comprising at least the following steps: (a) a first impregnating step which consists in impregnating at least once said support with a polar agent A, (b) a second impregnating step 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.
L'invention concerne un procédé d'imprégnation dit bi-phasique d'un support en .beta.-SiC à haute surface spécifique, ledit procédé comportant au moins les étapes suivantes : (a) une première étape d'imprégnation au cours de laquelle on imprègne au moins une fois ledit support par un agent polaire A, (b) une deuxième étape d'imprégnation au cours de laquelle on imprègne au moins une fois ledit support par un agent B moins polaire que l'agent A. Ce procédé permet la fabrication de nouveaux catalyseurs pour catalyse hétérogène.
