Learning outcomes
|
The aim of int this course of the chemical kinetics and catalysis is to acquaint students with the phenomena that accompany the chemical reaction in reactors, including their quantitative evaluation. Furthermore, the aim is to acquaint students with the description of important catalytic processes. Practical examples from this field, solved in lectures and seminars, should provide an understanding of the problems of chemical reactors and strategies for their use in the study of the kinetics of chemical reactions.
After completing the course, the student is able to independently solve more complex problems related to the kinetics of catalytic chemical reactions and chemical reactors.
