Preparation and Characterization of Cgo-Based Catalyst for Methanol Steam Reforming By Glycine-Nitrate Process

Methanol is a liquid fuel which can be produced from renewable energy sources and has high energy density. It has a low boiling point, a high H:C ratio of 4:1 without any C-C bond, therefore can be reformated at a relatively low temperature. In this work, we investigated the application of CGO(Gd:CeO 2 )-based catalyst for hydrogen production via methanol steam reforming. CGO-based powder material for a catalyst of methanol steam reforming was synthesized by glycine-nitrate process(GNP). GNP is one of the solution combustion synthesis methods, Metal nitrate and glycine were mixed with deionized water and solution heated by hot plate. After evaporation of water, solution converted to a viscous gel. The gel ignited with gases and powders. The synthesized powders were calcined for 4 hours at 800°C to remove moisture and impurity. Their properties such as micro structure, surface morphology, surface area and composition were investigated with XRD(X-ray diffraction), SEM(Scanning electron microscopy), BET (N 2 adsorption-desorption), EDS(Energy dispersive spectroscopy) and ICP-MS(Inductively coupled plasma mass spectrometry). The performance of catalysts was examined with reactor at 200 - 400°C range. The reactants and reaction products were analyzed by GC(Gas chromatography). The catalytic performance for hydrogen production was analyzed in terms of methanol conversion and selectivity of products.
