Abstract
AbstractThe purpose of this work is to develop a mathematical model of sulfuric acid alkylation of isobutane by olefins, taking into account the physical and chemical laws of the process. Due to the increased environmental requirements for fuel, the relevance of sulfuric acid alkylation of isobutane with olefins, as it allows us to achieve good results in this matter. Significant features of the technology that need to be taken into account when modeling are identified. The main schemes of transformations of sulfuric acid alkylation of isobutane by olefins are considered. The probability of all reactions is estimated from the Gibbs energy value. The model is a system of ordinary nonlinear differential equations. The direct problem was solved by Radau IIA method. During the simulation, heuristic optimization methods were used, the Electromagnetism like Algorithm and the Harmony Search algorithm were considered to minimize the deviation of experimental data from theoretical ones. The rate constants of the reaction under consideration are found. The foundations for further modeling of the entire chemical-technological process are laid.KeywordsMathematical modelChemical kineticsAlkylationHarmony Search AlgorithmElectromagnetism-like Algorithm
