摘要
在作者所建立的催化裂化提升管再生器数学模型的基础上,首次提出了再生器采用多段进气强化烧焦的构想。模拟计算结果表明,采用多段进气的再生方式,通过调节各段进气量和催化剂循环比,在待生剂碳含量为0.8～1.2w％的范围内,其再生效果可满足工业要求(再生器出口温度低于730℃,再生剂含碳量低于0.1w％),从而对提升管再生器这一新技术在工业上取得成功的可能性进行了全面的论证,为一项重大的工业试验提出了新的概念和理论分析。中国石化总公司北京设计院曾采用清华大学提供的上述新技术为长岭炼油化工厂设计提升管再生器。
A new method for catalyst regeneration of FCCU by supplying air at different levels of the riser regeneration has been proposed. The calculated results show that by using this method the carbon content of the regenerated catalyst can be less than 0.1w% and the outlet temperature of the riser can be below 730C while the coke on the spent cata- lyst ranging from 0.8 to 1.2w%. This method has been employed in the design of the riser regenerator in FCCU of Changling refinery by Beijing Design Institute of SINOPEC.
