A novel method for evaluating the thermal catalytic decomposition of organic compounds on a solid acid catalyst was developed using a capillary gas chromatography-flame ionization detector (GC-FID) equipped with a packed-capillary column. The thermal catalytic decomposition of various organic compounds was investigated by introducing gaseous or liquid organic compounds into a heated test tube packed with TiO2 particles. The resulting carbon monoxide (CO) and carbon dioxide (CO2) in the test tube were determined in a conventional capillary GC system with a methanizer after separation on a packed-capillary column. In the packed-capillary GC system, several parameters affecting thermal catalytic reactions of various organic compounds were successfully evaluated, such as the type of the catalysts and the effect of catalytic temperatures. Finally, a sequential decomposition of organic compounds was confirmed in the heated reaction tube packed with TiO2 particles.
利用配备填充毛细管柱的毛细管气相色谱 - 火焰离子化检测器（GC - FID），开发了一种评估固体酸催化剂上有机化合物热催化分解的新方法。通过将气态或液态有机化合物引入装有TiO₂颗粒的加热试管中，研究了各种有机化合物的热催化分解。在填充毛细管柱上分离后，在配有甲烷化器的传统毛细管GC系统中测定试管中生成的一氧化碳（CO）和二氧化碳（CO₂）。在填充毛细管GC系统中，成功评估了影响各种有机化合物热催化反应的几个参数，如催化剂类型和催化温度的影响。最后，在装有TiO₂颗粒的加热反应管中证实了有机化合物的顺序分解。
