催化重整装置反应器的建模与仿真
Modeling and simulation of continuous catalytic reforming reactor
摘要
Abstract
This paper developed a new kinetic model for catalytic reforming reactions based on the lumping theory and catalytic reforming reaction mechanisms. The developed model thoroughly analyzed the mutual reaction relationships among paraffin, cycloparaffin and aromatics, and covered most related reactions included in the continuous catalytic reforming progress. In order to resolve the challenges of the parameter estimation, the number of estimated parameters was decreased to 99 through reasonable supposition and the originally complex reaction network was split into several simpler sub-networks according to the number of carbon atoms. An iteration method combined of BFGS and SQP algorithms was then implemented to increase the accuracy of the parameter estimation. The developed model was used to simulate a continuous catalytic reforming reactor for verifying the model accuracy. And the simulation result showed that the model successfully predicted the reformate composition in the reactor and was proved to be able to meet the accuracy requirement of the industrial applications.关键词
