Ｐｈｉｌｌｉｐｓ公司认为，汽提器不仅能脱除待生催化剂携带的可挥发烃，还能控制进入再生器焦量及焦燃烧热量。它通过增加停留时间和提高温度的办法使化学吸附在催化剂上的烃缩合和环化，降低催化剂上焦的氢含量，同时产生富氢气体。汽提蒸汽降低烃的分压，并将轻烃气体从循 Phillips believes that the stripper can remove not only the volatile hydrocarbons carried by the spent catalyst, but also the amount of heat entering the regenerator and the amount of coke combustion. It increases the residence time and increases the temperature of the chemical adsorption on the catalyst hydrocarbon condensation and cyclization, reducing the coke on the catalyst hydrogen content, while producing hydrogen-rich gas. Stripping steam reduces the partial pressure of hydrocarbons and follows light hydrocarbon gases
