A PULSE STUDY GERMÁN SIERRA GALLEGO CATHERINE BATIOT-DUPEYRAT FANOR MONDRAGÓN Ingeniería lattice oxygen LaNiO3 perovskite auto combustion method Methane partial oxidation LaNiO3 perovskite was prepared by the selfcombustion method and tested as catalyst for CH4 activation using the oxygen lattice at 700°C and 800°C. Based on the nonstoichiometryexperiments, the perovskite formula is written as La 3+ Ni 3+ 0.37Ni 2+ 0.63O2.68. When unreduced LaNiO3d perovskite is used, only type oxygen species were responsible for the partial CH4 oxidation. Over non reduced perovskite high CH4 conversions to H2 and CO were obtained. CH4 conversion and H2, CO and CO2, selectivities under quasistationary conditions were 100%, 80%, 98% and 2 % respectively at 800°C. At the beginning of the reaction, a complete oxidation of methane to CO2 and H2O took place, whereas a partial oxidation to CO and H2 was observed after that period. In such conditions the H2/CO molar ratio obtained was 1.7, indicating a contribution of the parallel reverse water gas shift reaction. 2010 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49615099016 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.163 Vol.77 |
