Catalytic reforming is one of the most complicated processes in petroleum refining.Dynamic simulation procedure is concerned in this article which considered the reactors,heaters,separators as cell operation,a new kinetics nlodel involving twenty-three components wag built up to resolve the problem that countless differential equations were needed for the modeling of reacting process.Marquardt approach of objective function is implemented in optimization,while Range-Kuta(RK)approach of section iteration is applied for calculation.The model established accuratelv reflects the dynamic characteristics in unit operation,so as to provide useful supporting in forecast and optimize catalytic reforming.
