针对两段提升管催化裂解多产丙烯(TMP)工艺,在催化反应机理和TMP工艺特点的指导下,将反应体系划分成重油、柴油、汽油中的烯烃、汽油中的芳烃、汽油中的饱和烃、(丙烷+丁烷)、丁烯、丙烯、干气和焦炭共十个集总,建立了TMP工艺十集总动力学模型,并采用模拟退火法(全局)-最小二乘法(局部)-模拟退火法(局部)三层逐层寻优方法进行了参数估计。研究结果表明,TMP工艺十集总动力学模型可用来分析TMP工艺各产物分布规律,并考察操作条件对装置的影响,给装置操作优化提供指导。 Under the guidance of the catalytic reaction mechanism and TMP process characteristics, the reaction system was divided into heavy oil, diesel oil, olefins in gasoline, aromatic hydrocarbons in gasoline, saturated (Total), (hydrocarbon), (propane + butane), butene, propylene, dry gas and coke in a total of ten lumped, established Tcade ten kinetic models, and simulated annealing (global) - simulated annealing (local) three-layer optimization method for layer-by-layer parameter estimation. The results show that the TMP ten-g-kinetic model can be used to analyze the distribution of products in the TMP process, and study the influence of operating conditions on the device to provide guidance for device operation optimization.
