- W4387341738 abstract "Introduction. Because of high demand for polymer products, there are constantly modernized the technological aspects of their production, a huge share of which is based on the use of microheterogeneous catalytic systems. Physicochemical properties of polymer products can be improved through targeted hydrodynamic effect in turbulent flows. The study of physicochemical patterns of polymer product synthesis in the presence of modified catalytic systems is of great interest. Aim of the Article. The article is aimed at evaluating the efficiency of hydrodynamic influence in turbulent flows on the type of catalyst heterogeneity and the kinetics of polymer production processes. Materials and Methods. In the study of polymer synthesis processes, there is used a simulation approach to the system model description that is based on the idea of reproducing various scenarios of uninterrupted production and conducting the necessary empirical analysis. Parallel programming and cloud computing technologies are used in simulation modeling to increase computational speed. Results. A methodology for solving inverse problems has been developed to determine the influence of external factors on the kinetic activity and heterogeneity of active centers on the basis of known physicochemical information. The use of simulation modeling with the application of cloud computing technology makes it possible to unambiguously determine the type of kinetic heterogeneity in the conditions of averaging the reactive capacity of active centers. Discussion and Conclusion. Approbation of the new simulation approach to the solution of the inverse problem allowed evaluating the efficiency of the influence of the tube turbulent apparatus on the kinetics of producing polyisoprene in the presence of titanium catalyst and identifying the presence of two active centers: type ATi − lnM = 13.4, type BTi − lnM = 11.7, while the proportion of active centers type ATi is 0.91; type BTi – 0.09. Based on the data obtained, it becomes possible to formulate and solve inverse problems of identifying kinetic parameters for further model description of the system." @default.
