1 Thermodynamics and Rate Processes D.Kunzru Dept. of Chemical Engineering I.I.T.Kanpur

2 Importance of Chemical Reaction Engineering chemical reactor is usually the heart of any process traditional applications: petroleum refining, petrochemicals, pharmaceuticals, environmental pollution. emerging areas : microelectronics, advanced materials, biotechnology, energy from renewable resources, sustainable development, catalytic distillation. thorough understanding of the multiscale phenomena involved is required to design any reactor.

3 Objectives of a Comprehensive Course(s) on CRE After taking these courses a student should be able to : analyze and model an operating reactor design a new reactor troubleshoot develop the reaction kinetics for a new reaction ( most industrial processes involve heterogeneous reactions and proper understanding of kinetics, heat transfer, mass transfer and hydrodynamics is essential)

4 Suggested Topics Homogeneous Reactors Introduction: definition of rate of reaction; types of reactors; industrial reactions and reactors. Basic concepts in chemical kinetics: reaction rate constant; reaction order; elementary and nonelementary reactions. Determination of reaction kinetics from a mechanism: pseudosteady state hypothesis ;rate-controlling step; chain reactions; enzyme reactions. Experimental determination of reaction kinetics: different types of laboratory reactors; collection and analysis of rate data; differential and integral method of analysis.

5 Homogeneous Reactors (contd.) Isothermal reactor design for single reactions :batch reactor; semi-batch reactor; CSTR; plug flow reactor; multiple reactor systems.
