Biomass or landfill gas (LFG) is produced by anaerobicdigestion or fermentation of organic matter such as sewage sludge,MSW, etc. Biogas is a very complex gaseous mixture containingmainly CH4 and CO2, along with small amounts of N2, O2, H2S.Therefore, the emission of biogas to the atmosphere may contributesignificantly to the greenhouse effect. However, only a small portionof this biogas is used. In these cases, the LFG is used for heat orelectricity generation though combustion process. The production ofhydrogen from LFG for energy generation by fuel cells is apromising technology. In this approach, the LFG is converted tosyngas by the CO2 reforming of methane process (dry reforming ofmethane - DRM) followed by H2 purification steps. During the lastfew years, the DRM has been intensively investigated for theproduction of synthesis gas [1]. One of the main barriers of the dryreforming technology is the catalyst deactivation that occurs due tocarbon deposition during the high temperature process [2]. Therefore,the development of a catalyst resistant to carbon deposition duringCO2 reforming of CH4 is one of the main issues of this technology.Ni-based catalysts have been extensively studied for the DRM due toits low cost and high activity but this metal is prone to coking. Oneapproach to minimize or inhibit carbon formation is to control metalparticle size by the appropriated selection of catalyst preparationmethod. Therefore, the aim of this work is to study the performanceof Ni-based catalysts prepared from perovskite precursor for theproduction of hydrogen through DRM. The biogas was produced atthe sanitary landfill of Morro do C�u, situated in Niter�i � Brazil.
