根据工业ＴＬＥ的结构特点，作者设计和安装了一套研究ＴＬＥ结焦的实验装置，研究了轻柴油裂解装置中ＴＬＥ的结焦过程。提出了轻柴油裂解时ＴＬＥ结焦机理为传质、冷凝一表面缩聚反应机理。首次证实了在ＴＬＥ结焦过程中存在着特定的转折温度。当壁面温度高于转折温度时，传质、冷凝过程为结焦过程的控制步骤；反之，表面缩聚反应过程为控制步骤。根据上述ＴＬＥ结焦机理建立了ＴＬＥ结焦模型，并对工业装置进行了模拟，模拟结果与工业实测数据吻合。
According to the structural characteristics of industrial TLE, the author designed and installed a set of experimental devices for studying TLE coking, and studied the coking process of TLE in the light diesel oil cracking device. The mechanism of TLE coking in light diesel oil cracking was proposed as mass transfer and condensation-surface polycondensation reaction mechanism. For the first time, it was confirmed that there is a specific transition temperature during the TLE coking process. When the wall temperature is higher than the transition temperature, the mass transfer and condensation process are the control steps of the coking process. Conversely, the surface condensation reaction process is the control step. According to the above TLE coking mechanism, a model of TLE coking was established, and the industrial plant was simulated. The simulation results are in good agreement with the industrial measured data.
