In order to search for the law and knowledge of desulphurization process to make decision support for the process,Radial Based Function（RBF） neural network is used as modeling tool.According to the difficulty in determining RBF center and width in the process of modeling,based on the analysis of ant algorithm mechanism,this paper presents that intelligent ant algorithm can be used to make self-adaptation selection for the center and width of RBF neural network model so as to reach optimal balance between the training accuracy and generalization and further to increase predication accuracy of the model.On the basis of analyzing the principle of desulphurization technology and by effective data preprocessing,simulation analysis is conducted,the forecasting accuracy of the model is better than traditional static model for desulphurization,and this model has certain practicability and popularization value.
