Intended Learning Outcomes

At the completion of the course, the student will be able to

1

identify and determine the parameters in kinetic rate expressions for homogeneous and heterogeneous reactions and for elementary and non-elementary reactions.

2

formulate and apply the design equations for the three ideal reactor models (batch, CSTR, and plug flow) in the presence of both single and multiple reactions.  

3

formulate and apply the energy balance equation to the ideal batch, CSTR and plug flow reactor models, and determine required heating and cooling loads, in the presence of both single and multiple reactions

4

formulate and apply the design equations and rate laws for catalytic reactors

5

select the appropriate reactor type for a given chemical conversion and size it to meet operational goals.

6

synthesize an appropriate multi-reactor sequence to meet operational goals

7

identify and analyse additional problems which may be solved by the methods of chemical reaction engineering

8

transform problems in chemical reaction engineering into mathematical models and, if necessary, choose suitable computer package (for example MATLAB) for solving those models on a computer

9

design and conduct experiments to generate data, analyse the data and obtain information required for the design and scale-up of chemical reactors
