co/ce0.5zr0.5o2催化剂的制备及甲烷部分氧化制合成气
, PP. 418-423
Keywords: ce0.5zr0.5o2固溶体,钴,甲烷部分氧化,合成气
Abstract:
？利用共沉淀法制备了具有介孔结构的ce0.5zr0.5o2固溶体载体,然后浸渍不同质量分数(10%、20%、30%)的活性组分钴,制备了系列co/ce0.5zr0.5o2催化剂。利用n2物理吸附(bet)、x射线粉末衍射(xrd)、h2-程序升温还原(h2-tpr)、扫描电子显微镜(sem)、透射电子显微镜(tem)、程序升温氧化(tpo)和热重(tg)等手段对制备和反应后的催化剂进行了表征,研究了它们对甲烷部分氧化制合成气反应的催化性能。研究结果表明,铈锆固溶体负载的钴比较容易被还原,该系列催化剂具有较高的活性和对h2及co的选择性,且随co含量的增加,催化剂的活性和对h2和co的选择性得到提高的同时,也增强了催化剂的抗积炭性能。
