Courses

CHBE 471 - Biochemical Engineering
Chemical engineering analysis is increasingly being applied to problems in biotechnology, bioprocessing and the life sciences.  As a result, chemical engineers with the required understanding of biological systems are valuable to many pharmaceutical and biotechnology companies.  This course is intended to serve as a first introduction to basic biological principles for chemical engineering students, with an emphasis on mathematical descriptions of enzymatic reactions, cellular growth and metabolism, bioreactor kinetics and bioseparations.

CHBE 424 - Chemical Reaction Engineering
This course is an introduction to chemical kinetics, chemical reactor design, and the interrelationship between transport, thermodynamics, and chemical reaction in open and closed systems. Students learn how to construct models based on experimental data and to use these models to design reactors for a wide variety of chemically reacting systems. These skills are critical for all chemical engineers.

Prof. Kraft developed the following lecture presentations based on the material in Scott Fogler's textbook, "Elements of Chemical Reaction Engineering" (Prentice Hall). Instructors may download these presentations and adapt them for their own teaching purposes; please credit the source.
