P3. (5 points) FBR problem Complete the problem from Fogler for Oxidation of Ammonia (hand out in class) 1. SUBMIT an excel workbook that is commented for solving these types of problems. 2. SUBMIT a modified solver diagram and accompanying equation sheet that matches your revised algorithm 3. DISCUSS what things you think need to be explained or detailed better and their importance with regards to designing a FBR. 12. DIFFUSION AND REACTION IN POROUS CATALYSTS Professional Reference Shelf Example CD12-4: Catalytic Oxidation of Ammonia Massimilla and Johnstone 25 studied the catalytic oxidation of ammonia in a fluidized-bed reactor. Under their experimental conditions, the reaction was first order, dependent only on the ammonia concentration, and without a significant change in volumetric flow rate. In one of their runs, 4 kg of catalyst was used with a gas flow rate of 818 cm3/s at reaction conditions. A conversion of 22% of the entering ammonia was obtained. Predict this conversion using the Kunil-Levenspiel model.
