The software package for simulation of continuous catalytic reforming reaction is developed by using the mathematical model of continuous catalytic reforming reactor, etc. The software package for simulation of continuous catalytic reforming reaction is validated by simulation calculation of domestic ultra-low pressure continuous catalytic reforming industrial unit. The absolute deviations between the yields of C5^+ liquid products, aromatics and pure hydrogen and the corresponding actual values are 0.50%, 0.94% and 0.03%, respectively. The calculated value is in good agreement with the actual value, which shows that the software package has good reliability and accuracy and meets the requirements of industrial application. The software package for simulation calculation of continuous catalytic reforming reaction has complete calculation functions. It can provide comprehensive and detailed basic design data for the feasibility study and design of the unit according to the composition and properties of reforming feedstock and the requirements of the reforming products provided by the users. The software package also provides an effective tool for improving the design efficiency and optimizing the design scheme of continuous catalytic reforming units. It can also be used to study the effect of operating conditions(such as reaction temperature) on Liquid products yield and aromatic hydrocarbons and hydrogen yield.
