Partial oxidation of methane on co-precipitated Ni–Mg/Al catalysts modified with copper or iron Authors Djamila Kaddeche, Abdelhamid Djaidja, Akila Barama Publication date 2017/6/1 Journal International Journal of Hydrogen Energy Volume 42 Issue 22 Pages 15002-15009 Publisher Pergamon Description Methane transformation to hydrogen and synthesis gas (CO + H2) by heterogenous catalysts can play an important role to secure the supply of energy, chemicals and fuels in the future. Methane is the main constituent of natural gas and biogas and it is also found in crystalline hydrates at the continental slopes of many oceans. In view of this vast reserves and resources, the use of methane as chemical feedstock has to be intensified. In this present work, (NiMg)Al catalysts doped with Fe or Cu, prepared by co-precipitation method and characterized by different techniques, were studied in the partial oxidation of methane (Treaction = 750 °C, CH4/O2 ratio = 2). The effect of catalyst composition and pre-treatment conditions of these catalysts were investigated. Also, these catalysts show a very high activity and selectivity in the partial oxidation reaction, which depends on the conditions of catalysts preparation. The
