| Abstract: | Bifunctional catalyst Mo2C/Al2O3 was prepared by precipitation method and carbonized by programed heating. Its catalytic effects on steam reforming of dimethyl ether (SRD) for hydrogen production were investigated. Materials of catalyst carriers and molar ratio of Mo2C/Al2O3, along with reactants concentration were studied to show their influence on activity of catalysts. It was found that catalyst with Mo/Al = 1/1 had superior catalytic activities for SRD reaction, the optimum feeding was H2O/DME = 5/1, and a relatively higher catalytic performance achieved at 400oC. |
| Keywords: | molybdenum carbide dimethyl ether reforming for hydrogen production |
