摘　　要：在固定床加氢试验装置上研究催化裂化汽油馏分烯烃加氢反应,初步探索了烯烃加氢反应机理。结果表明,烯烃加氢反应符合Langmuir-Hinshelwood机理,以此反应机理为基础,建立了按照碳数分布的烯烃加氢动力学模型,并采用龙格-库塔计算方法对模型参数进行了求解。Hydrotreating reactions of olefines in FCC naphtha（FCCN） were discussed and three reaction mechanisms for olefines hydrosaturation in FCCN were studied.The data were obtained by the hydrotreating real FCCN feeds in pilot plant unit.Results showed that olefine reactions agreed with Langmuir-Hinshelwood（L-H） mechanism.Based on that,dynamic models hydrosaturation reactions of different carbon-number olefines were set up.As calculated results by the L-H equation,the olefin adsorption equilibrium constant increased with the augment of olefin carbon number,and the hydrogenation reaction speed constant decreased.Runge-Kutta method was used to calculate the parameters of the models.
