MODIFIED PEROVSKITE CATALYST FOR AQUEOUS PHASE REFORMING OF GLYCEROL AND THE PREPARATION METHOD

摘要

The present invention relates to an improved perovskite-based composite oxide catalyst in which a transition metal is dipped in order to improve the selectivity of hydrogen and remarkably decrease the selectivity of methane and carbon monoxide as byproducts. Moreover, the present invention relates to a method for selectively producing hydrogen by means of the C-H decomposition and C-O maintenance of glycerol using the metal oxide catalyst. The improved perovskite-based catalyst (NixMy/LaCexAl1-xO3) in which nickel and a second transition metal are dipped is applied to the reaction of glycerol so as to maintain the high conversion rate of glycerol and the high selectivity and yield of hydrogen. Accordingly, the catalyst can be usefully used as a catalyst for converting glycerol which is generated during a biodiesel process into high value-added hydrogen and as a catalyst for a reaction process of synthesizing high value-added hydrogen.
