Abstract In this work a simulation of detailed steady state model of an industrial fluid catalytic cracking (FCC) unit with a newly proposed six-lumped kinetic model which cracks gas oil into diesel, gasoline, liquefied petroleum gas (LPG), dry gas and coke. Frequency factors, activation energies and heats of reaction for the catalytic cracking kinetics and a number of model parameters were estimated using a model based parameter estimation technique along with data from an industrial FCC unit in Sudan. The estimated parameters were used to predict the major riser fractions; diesel as 0.1842 kg-lump/kg-feed with a 0.81% error while gasoline as 0.4863 kg-lump/kg-feed with a 2.71% error compared with the plant data. Thus, with good confidence, the developed kinetic model is able to simulate any type of FCC riser with six-lump model as catalyst-to-oil (C/O) ratios were varied and the results predicted the typical riser profiles.

某工业流化催化裂化装置六块体动力学模型参数估算

摘要 在这项工作中，使用新提出的六集总动力学模型模拟工业流化催化裂化 (FCC) 装置的详细稳态模型，该模型将瓦斯油裂解为柴油、汽油、液化石油气 (LPG)、干气和焦炭。 . 使用基于模型的参数估计技术以及来自苏丹工业 FCC 装置的数据，估计了催化裂化动力学的频率因子、活化能和反应热以及许多模型参数。估计参数用于预测主要立管部分；与工厂数据相比，柴油为 0.1842 kg-块/kg-饲料，误差为 0.81%，而汽油为 0.4863 kg-块/kg-饲料，误差为 2.71%。因此，怀着良好的信心，
