| Abstract: | In this paper, back-propagation neural network was applied to the system of LPG aromatization. The neural network model of this reacting system was established under given reacting conditions. The network＇s training results have achieved present requirements and the network output could match the experimental data well. This model could predict products distribution of the LPG aromatization system under given conditions. The results could provide some reference for further development on LPG aromatization, prediction of product distribution and simulation of the industrial processes. |
