The bi- and tri-reforming processes for methane employ the combination of dry reforming, steam reforming and partial oxidation reactions in a single reactor in order to increase process efficiency, have less environmental impact and produce a synthesis gas with flexible H2/CO ratio for further applications. The process requires an active, selective and stable catalyst in a complex reaction environment due to the diversity of reactants. In this context, the project aims to synthesize and evaluate Ce, Sr and Co nanoparticle catalysts supported on carbon nanotubes, as well as mixed oxide precursors of the perovskite type with ABO3 structure, where the A sites are replaced with La, Nd, Sr, Ce cations, and the B sites with Ni, Co and Cr cations. These materials exhibit high thermal stability over a wide temperature range, as well as high oxygen ion storage capacity and conductivity which prevents coke formation.
