一段法缓和加氢裂化动力学研究

KINETIC STUDY ON SINGLE STAGE MILD HYDROCRACKING

对胜利蜡油一段法缓和加氢裂化过程,提出了四集总动力学模型,用修正停留时间的方法正确处理了加氢脱氮与加氢裂化之间的关系,并对雪弗龙加氢裂化动力学模型进行扩展,使其可以应用于一段法缓和加氢裂化过程。由实验数据求出了模型参数,并对模型进行了验证。

A four-lump model was derived for single stage mild hydrocracking of Shengli VGO.The effect of hydrodenitrogenation on hydrocracking can be involved in the model by introducing the effective residence time for hydrocracking.Some modifications were made on the kinetic model developed by Bruce E.Stangland(Chevron Research Company)to make it applicable to the sigle stage mild hydrocracking.The parameters of the models were determined from experimental data.
