Lumping Kinetic Model for New Catalytic Cracking of MIP Process

摘要: 依据多产异构烷烃（MIP）工艺两个反应区特点，从催化裂化反应机理出发，以工业装置实测数据为基础，建立了MIP工艺10集总反应动力学模型。该10个集总为：原料饱和分(SS)、芳香分(SA)、胶质及沥青质(SR)、柴油(D)、汽油中饱和烃(GS)、烯烃(GO)、芳烃(GA)、液化气(LPG)、气体(Gas)和焦炭(C)。求取了40组动力学参数，并应用工业实测数据进行了验证，结果表明：所建模型能较好地预测MIP工艺主要产品分布及汽油烃族组成，符合MIP工艺的反应规律，对MIP工艺的完善和优化具有参考价值。

Abstract: Based on the mechanism of heavy oil catalytic cracking and the features of two reaction zones of maximizing isoparaffins (MIP) process, a 10lumped kinetic model was established according to the data from a commercial unit of MIP which included saturates(SS), aromatics(SA), resin and asphaltene(SR) in the feed, diesel(D), gasoline saturated hydrocarbons(GS), gasoline olefins(GO), gasoline aromatics(GA), liquefied petroleum gas(LPG), dry gas(Gas) and coke(C). 40 Sets of kinetic parameters were calculated and tested by industrial data. The results showed that the model predicted well the main products, especially hydrocarbon group composition of gasoline, and reflected the catalytic cracking reaction rule. This model can guide the optimization of MIP process.
