heat and mass transfer with parallel reaction criteria of Mears.
Residence Time Distribution, E (t) and F (t) functions for CSTR, PFR and laminar flow reactor, mean residence time; micromixing and complete segregation and maximum blending; one-parameter models for non-ideal reactors: tanks-in-series and convection-dispersion model; Taylor-Aris dispersion; open-open and Danckwerts boundary conditions associated with E (t) functions; convection-dispersion model with reaction in steady state; models for non-ideal reactors via combination of ideal reactors.

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

Extended information about the assessment
There are 5 graded interim quizzes in Oncourse that each count for 20% of the final grade. Every week students have 2 opportunities to take a graded quiz. Only the best grade counts: Students can always improve their score. Each graded quiz must be completed with a grade >50 (5,0) in order to get access to the next one. Multiple quizzes can be attempted in one time-slot in any order, as long as the requirements are met. However, a specific quiz cannot be retaken in the same time-slot. Students have completed the course when the requirements are met and the average is at least a 5,5.

Learning outcomes

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.
