| 摘 要： | 采用浸渍法制备了助剂Ce掺杂的Ni/Al_2O_3催化剂,用于甘油重整气甲烷化反应,分别采用BET、XRD、H_2-TPR、CO_2-TPD等手段对催化剂进行了表征,并考察了Ce掺杂量、甲烷化温度、在线运行时间对Ce掺杂Ni/Al_2O_3催化甲烷化性能的影响。结果表明,掺杂的Ce会优先占据Ni/Al_2O_3催化剂的微孔,抑制活性组分Ni与载体Al_2O_3相互作用而生成尖晶石NiAl_2O_4,促进表面高度分散的活性Ni的生成,其催化还原性、甲烷化性能得以提高。3%(w)Ce掺杂的Ni/Al_2O_3在甘油重整气甲烷化反应中最佳温度范围为275~300℃,CO和CO_2转化率分别可达99%和75%以上,每千克甘油经水蒸气重整、甲烷化反应后生成的甲烷量达到570L以上。
