Course Description
Course objectives:
-
Identify and determine the parameters in kinetic rate expressions for
homogeneous (and heterogeneous) reactions and for elementary and
non-elementary reactions.
-
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.
-
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.
-
Formulate and apply the design equations and rate laws for catalytic
reactors.
