Planning and organizing skills are an integral part of this course. There are specific assignments which will be assessed during the course, such assignments will help you to develop your skills, you will be guided to receive and give feedback to improve such skills. After this course you will be able:

• To plan and organize time and efforts

Learning objectives:

After completion of this course, the student is able to :

· Apply conservation laws of mass and energy for setting up model equations for the design of chemical reactors.
· Apply these model equations for the design of chemical reactors for given rate equations of single and multiple reactions.
· Apply energy balance equations for the design of non-isothermic reactors. Determine the desired reactor temperature as related to the conversion, as well as the stability of the reactor for especially exothermic reactors.
· Design the fixed-bed reactor for heterogeneous catalyzed reactions,
· Estimate the importance of diffusion and reaction in the catalytic particle.
· Set up and evaluate model equations for non-ideal reactors based on data on residence time distribution.
