The aim of the course is to analyze the processes that will lead to the calculation of chemical reactors by understanding the chemical kinetics and transport phenomena occurring in reactive systems. Units included: Homogeneous Chemical Process Techniques (Thermodynamic Chemical Reactions, Continuous Work Reactors, etc.). Technique of Heterogeneous Chemical Processes: Gas-Solid Reactions, Fluid-Fluid Reactions, Three-Phase Reactions, Absorption Reactors.
