Hybrid Modeling for Deactivation of BPA Catalyst
摘要
Abstract
During the production of bisphenol A (BPA), the used ion exchange resin catalyst will be deactivated with the changes of reaction temperature, operation time, ratio of phenol to acetone in feed and load of production. In order to monitor the change of catalyst activity online, based on mathematical regression and support vector machine (SVM), a hybrid soft sensing model for catalyst activity of BPA production was established. During the establishment of the above model, a quadratic polynomial was applied for the mathematical regression of the decreasing trend of the catalyst activity; and based on it, the SVM was used for the consideration of the catalyst activity fluctuation caused by the reaction temperature, ratio of phenol to acetone and feed load. Finally a soft sensing model used for the estimation of the BPA content in the reactor outlet of the BPA production was established too. The results of the model simulations and the industrial production process show that the established soft sensing model for the catalyst activity of BPA production can yield satisfactory estimation results and meet the needs of industrial production process.关键词
