SHELL IMPREGNATED CATALYST AND PROCESS FOR PRODUCING A SHELL IMPREGNATED CATALYST BODY |
摘要 |
The present application relates to a process for producing a catalyst,said process comprising the steps of: providing a carrier and following modifying said carrier by a first impregnation with at least one alkaline earth metal in a first metal precursor solution. The first metal precursor is decomposed to form at least one metal oxide or metal hydroxide thereby obtaining a modified carrier and a second impregnation is carried out by incipient wetness by a second precursor solution comprising at least one metal Me in a second solution. Finally the second precursor is decomposed thereby obtaining a catalyst body having an enrichment of the at least one metal Me in the outer shell of the catalyst body, said at least one metal being present in a concentration having either as an egg-shell profile or a hammock profile. |
