Abstract: The filling, pretreatment of new catalyst of BASF 0466 and the changing of hot spot temperature when the material entered the reactor were investigated. It was found that the activity of catalyst can be optimized by adjusting the air flowed into the reactor and the reactor temperature in pretreatment of the catalyst|while the reaction has begun, the hot spot temperature mainly focused on the catalyst layer of CL4, as the reaction proceeded, the hot spot temperature is gradually transferred to the position of the catalyst layer of CL1. The hot spot temperature from 3 050 mm to move to the position of 650 nm and 550 mm. The hot spot temperature rises from 410.5 ℃ to 431.5 ℃, the hot spot temperature increase of 5.1%.

摘要： 通过对BASF04-66型催化剂的填装、预处理以及进料后反应器热点温度位置的变化等进行分析研
究,得出在催化剂预处理中,调节进入反应器的风量以及反应器温度可使催化剂活性最优;在反应刚开始进行时,热
点温度位置主要集中在CL4催化剂层,随着反应的进行,热点温度位置逐渐转移至CL1催化剂层,即热点温度位置
从3050mm 移动至650、550mm 处。热点的温度从410.5℃上升至431.5℃,热点温度提高了5.1%。
