- can you show me step for step?arrow_forwardFundamentals of Energy Systems HW5 Q6arrow_forwardProblem 1 Marks: 60 Section: 1a): 30 marks, Section 1b):30 marks A laboratory scale fluidized bed is considered for studying a catalytic ozone decomposition. a) It is requested to derive model equations under the following assumptions: ■ Operation of the catalytic reactor under steady state conditions, There is no influence of thermal ozone decomposition reactions. The fluidized bed includes bubbles and dense phase. □ The dense phase can be simulated using a CSTR The fluidized bed bubbles contain catalyst particles and can be simulated as a DSTR (batch). □ The jets contain particles and can be simulated with a PFR. The influence of the freeboard has to be considered using a PFR model. The available catalytic reaction rate model is r (moles/gcat.s)= -k CA b) Same than on a) under unsteady state conditions, using an absorbable and reactive tracer. Note: A step-by step derivation of the model equations is required here. A quick answer will not do. Problem 2 Marks: 40 Section 2a: 30 marks,…arrow_forward
