摘　　要：三乙胺作为一种含氮挥发性有机物,其催化燃烧处理对相关企业及行业有重要意义。以ZSM-5及过渡金属Co、Cu、Fe改性ZSM-5分子筛为催化剂,研究催化剂表面酸性、比表面积等对催化性能的影响。结果表明,三乙胺在催化剂上完全转化所需的最低温度依次为Co-ZSM-5(220℃)<Cu-ZSM-5(280℃)<ZSM-5(300℃)<Fe-ZSM-5(320℃)。在反应温度(220~240)℃时,Co-ZSM-5分子筛对CO_(2)选择性达到98%,N_(2)选择性达到90%,生成的废气较少。Triethylamine is a kind of nitrogenous volatile organic compounds and its catalytic combustion treatment is of great significance to relevant enterprises and industries.In this paper,ZSM-5 and transition metals Co,Cu and Fe modified ZSM-5 were used as catalysts to study the influence of surface acidity and specific surface area on catalytic performance.The lowest temperature required for complete conversion of triethylamine on the catalyst is in the order of Co-ZSM-5(220℃)<Cu-ZSM-5(280℃)<ZSM-5(300℃)<Fe-ZSM-5(320℃).Co-ZSM-5 has 98%selectivity for CO_(2) and 90%selectivity for N_(2) at(220-240)℃,resulting in less exhaust gas.
