oms-2/al2o3/堇青石整体式催化剂的制备及其催化性能研究
, PP. 1115-1121
Keywords: 氧化锰,整体式催化剂,二甲醚,催化燃烧
Abstract:
？以al2o3/堇青石蜂窝陶瓷为载体,氧化锰八面体分子筛(oms-2)为活性组分,采用涂覆法制备了系列整体式催化剂。考察了黏合剂种类和活性组分涂覆次数对二甲醚(dme)催化燃烧性能的影响,并对催化剂进行xrd、bet、sem、h2-tpr、o2-tpd等表征。结果表明,以甲氧基聚乙二醇为黏合剂经一次涂覆制备的整体式催化剂的性能最佳,活性组分oms-2以相互交织的簇体均匀分布在载体上,并与al2o3之间存在较强的相互作用。涂层的添加有效增加了催化剂的比表面积,提高了催化剂的性能,最佳催化活性t90为257℃。
