Course overview and goals
In addition to the production of basic chemicals in conventional chemical processes, it is necessary to efficiently carry out targeted chemical reactions for various reactions, including the chemical conversion of carbon dioxide and the utilization of biomass. For this purpose, it is important not only to understand the reaction phenomena in a reactor but also to select and design an appropriate reactor. In Chemical Engineering 3 (Fundamentals of Reaction Engineering), students learn basic methods to quantitatively evaluate reaction rates and accompanying changes in mass in homogeneous reactions in gas and liquid phases in batch and continuous reactors.
First, the definition of reaction rate and the derivation of reaction rate equation will be introduced. Then, the design equation of the reactor is derived from the stoichiometric relation of the reaction and the mass balance equation. Based on this basic knowledge, students learn how to design batch reactors and continuous reactors (tank reactors and tube reactors) and how to apply them to actual processes.
Course description and aims
By the end of this course, students will be able to:
1) Derive reaction rate equations using steady state approximation and rate-limiting step approximation
2) Understand the mass-balance equation and derive the design equations for reactor design in batch-, continuous stirred tank- reactor and tubular-reactors
3) Understand the characteristics of batch-reactor
4) Understand the characteristics of continuous stirred tank-reactor (CSTR)
5) Understand the characteristics of tublar-reactor (Plug-flow reactor, PFR)
6) Understand the effects of reactor volume and reaction time on the progress of reaction, changes in conversion and product yield

Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
