1. 毕业设计（论文）的内容和要求
本课题开展堇青石负载稀土基脱硝催化剂的制备工艺探索，研究涂层前驱体的选择，涂层与载体高结合强度，碱金属离子中毒影响，催化剂负载量和脱硝性能之间的关系以及堇青石负载稀土基脱硝催化剂的反应机理。
（1）在第1章引言部分，通过文献阅读和总结分析，给出如下内容：TiO2、Al2O3等其他催化剂载体相比，堇青石具有机械强度高和成本低廉等优势，但堇青石涂层易受柴油车尾气中碱金属离子影响，造成碱金属离子中毒，因此堇青石负载稀土脱硝催化剂设计时还需考虑催化剂涂层碱金属离子影响，如何在保证堇青石与涂层高强度结合的基础上，提高堇青石载体的抗碱金属离子中毒性能，从而提高堇青石负载稀土脱硝催化剂的性能，是本课题的研究重点之一。
（2）在第2章试验方法设计部分，针对文献研究中发现的问题，考虑到柴油车尾气中不仅含有NOx，同时还有一氧化碳、碳氢以及水蒸气等组分，因此设计堇青石负载稀土基脱硝催化剂时还需要考虑复杂烟气组分对催化剂脱硝性能的影响，保证催化剂在复杂工况烟气组分下的脱硝活性。
