CHE 301: Chemical Reaction Engineering (4)

Learning Objectives:

Chemical reaction engineering (CRE) course will provide the basic concept of chemical kinetics such as homogeneous and heterogeneous reactions, rate of reaction, order and   molecularity of reaction. It also gives an idea to design a chemical reactor using the concepts of calculus, differential equations, basic chemistry, and thermodynamics with energy and material balances. This course will help the students to understand the chemical kinetics, concepts of various reactors and design of ideal reactor for single and complex reaction problems.

Course Contents:

Introduction: introduction to chemical reaction engineering with material balances for rate of a chemical reaction, mathematical expression of reaction rate for steady and unsteady flow stirred-tank reactors, tubular reactors and packed bed reactor, design equations for flow reactors.

Rate laws, kinetic and stoichiometry: basic definition and relative rates of reaction, kinetic of elementary and non-elementary reactions, nth-order kinetics, rate equations with multiple rate constants, shifting-order kinetics, interpretation of batch reactor data for simple and complex reactions, analysis of Arrhenius equation.

Design of isothermal reactor: constant and variable volume reactors, mole balances and design structure of isothermal reactors; design of continuous stirred tank reactors (CSTRs) for batch, series and parallel operations; design of tubular reactor.

Homogeneous reactions: introduction to homogeneous reaction in gas- and liquid-phases, performance equations for batch, semi-batch, continuous-flow, stirred-tank and plug-flow reactors.

Heterogeneous reactions: introduction to non-catalytic and catalytic reactions, definition of catalyst, catalyst properties, classification of classification of catalysts and catalytic reactors, kinetically-controlled and diffusion-controlled regimes, determination of rate controlling steps.

Residence time distribution (RTD) for reactor: characteristic of RTD, measurement of RTD, RTD in ideal reactors (stirred tank and plug flow reactor).
