Mo2CAl2O3的制备及其催化二甲醚水蒸气重整性能研究
摘要：摘要通过浸渍沉淀法结合程序升温碳化法制备了Mo2C/Al2O3复合催化剂,并应用于二甲醚水蒸气重整催化体系的研究。考察了二甲醚水解催化载体、水解功能组分Al2O3与重整功能组分Mo2C的比例、反应物浓度对复合催化剂活性的影响。结果表明,β-Mo2C与γ-Al2O3载体以Mo/Al = 1/1耦合后能够高效催化二甲醚重整制氢,其最佳进料水醚比为5,最适反应温度为400℃。
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.
