Abstract
Abstract Catalytic Steam reforming of ethanol (SRE) is a promising method for the generation of H2 as a clean carrier of energy. In this study, the impregnation method was deployed to prepare mono and bimetallic catalyst Nix-Co(10-x) (x = 10, 9, 8, 5 and 0) loaded on MCM-41 nanoparticles as the catalyst for the SRE reaction. The characteristics of the synthesized catalysis were identified using BET, XRD, EDS, FESM, and TGA/DTA analysis in a fixed bed micro-reactor, the gases were constantly monitored by using gas chromatography (GC). The purpose of this project is to optimize the reaction conditions using synthesized catalysts and to find the best catalyst. The effects of reaction temperature (420–500 °C) and molar ratios of steam to ethanol (S/E = 2, 3 and 5) were studied in detail over this catalyst. According to the results, the performance of bimetallic catalysts is very high compared to mono metal catalyst. Between mono metal catalysts Nickel was active rather than Cobalt. Ni9 Co1/MCM-41 catalysts displayed the best catalytic performance, so that the conversion of ethanol was 90% and highest hydrogen yield of 80% were achieved at the temperature of 490°C, S/E = 5 and under the atmospheric pressure.
