利用差热-色谱联用装置对临氢脱烷基催化剂进行温度扫描,用在线色谱测定在温度程序控制下反应产物随反应温度的变化,达到快速筛选催化剂的目的。对快速获得催化剂稳定性信息问题进行了探讨。
The temperature of the hydrodealkylation catalyst was scanned by differential thermal-chromatographic apparatus, and the change of the reaction product with the reaction temperature under the temperature program was measured by on-line chromatography to achieve the purpose of rapid screening of the catalyst. The rapid access to information on the stability of the catalyst was explored.
