The catalyst presented a relevant performance in sulphur-free conditions, not only in activity but also in stability.The test carried out in the presence of DMS showed that thismultimetallic catalyst has an acceptable sulphur-resistance.The alternating operation between BRM/SMR allowed tooperate in optimal conditions improving the stability of thesample, probably due to the gasification of coke deposits,which partially regenerates the active sites blocked by thesulphur compound. The approach presented in this work,multimetallic sample together with alternated reaction conditions, is a promising technology capable of carrying out biogas self-reforming process without any pretreatment orcomposition adjustment
