| 中文摘要 | 采用负载型Rh/MgO/γ-Al2O3催化剂研究了毫秒级甲烷蒸汽重整过程,在水碳比为1和3的条件下,详细考察了反应温度、空速和催化剂Rh含量对反应转化率和选择性的影响。研究结果表明,Rh/MgO/γ-Al2O3催化剂在毫秒级操作条件下具有良好的催化性能,使用5%(质量分数)Rh催化剂,在水碳比3、反应温度1150K、空速641.11 L·(gcat)-1·h-1时,CH4转化率约90%,CO2选择性约20%,毫秒级接触时间反应行为即可接近热力学平衡。高温有利于毫秒级甲烷蒸汽重整过程。; Steam reforming of methane(SRM)on Rh/MgO/γ-Al2O3 catalyst with contact time of milliseconds for producing hydrogen was studied.The effects of reactor temperature,space velocity and rhodium loading were investigated in detail at the H2O/CH4 molar ratio of 1 or 3.The results showed that Rh/MgO/γ-Al2O3catalyst was extremely active and stable during the process of methane steam reforming.Under the conditions of rhodium loading of 5%(mass),H2O/CH4 molar ratio of 3,reaction temperature at 1150 K and space velocity at 641.11 L·(g cat)-1·h-1,methane conversion could reach 90% and the selectivity to carbon dioxide was about 20%.The reaction performance approached nearly thermodynamic equilibrium within milliseconds contact time.A high reaction temperature benefited the progress of the reaction.; 中石油基础研究基金项目 |
