Software implementation of the algorithm for finding the optimal temperature condition of the catalytic process

The paper describes the software for solving problems of optimal control of the catalytic process in an ideal mixing reactor. The general form of the formulated optimal control problem is based on a mathe-matical model of the process in an ideal mixing reactor. The refrigerant temperature is considered a control parameter; its values are limited. In order to solve the problem numerically, the paper presents a step-by-step algorithm based on the evolutionary method of artificial immune systems. The method of artificial immune systems for solving optimal control problems makes it possible to obtain an ap-proximate solution to the problem in a time that is acceptable from a practical point of view. The formulated algorithm is a basis for the developed application for the catalytic reaction of α-methylstyrene dimerization in the presence of the NaHY zeolite catalyst, whose products (linear dimers) are widely used in industrial production. To calculate the process in an ideal mixing reactor, the program implements a number of numerical methods. The software tool allows the user to customize both the catalytic process parameters and the parameters of the algorithm of the artificial immune system method. The user sets the optimization criterion during the program operation, which makes it possible to use it for various formulations of the tasks of the catalytic process of α-methylstyrene dimerization and to obtain a set of optimal concentrations of substances and optimal temperature conditions that correspond to the specified process indicators. The paper gives a solution to the problem of finding the optimal temperature condition for the considered catalytic process, the optimality criterion of which is the achievement of the maximum yield of linear dimers with a minimum yield of cyclic dimers and trimers.
