Reaction rate and conversion rate are the key factors to improve production efficiency in chemical production process.Through analyzing the chemical production process,this paper discusses how to speed up the reaction rate and improve the product conversion rate.Firstly,based on the activation energy of chemical reaction,the feed ratio segmented control method is proposed.And then based on the simulation experiment of chemical process,the control method of catalyst dosage is proposed.Finally,the chemical production model and simulation test platform based on SMPT-1000 are established to simulate and verify the proposed method.The results show that the control method of variable feed ratio and catalyst dosage can accelerate the reaction rate of chemical production process and improve the reaction conversion rate compared with the traditional fixed amount method.
