Oxidation of Ammonia (NH3) is taking place through the following four gasphase reactions in a PFR. The reactions are simultaneous on a metal oxidesupported catalyst. 1: 4NH3+5O24NO+6H2O (1 1st order for NH3 and 2nd order for O2 ) 2: 2NH3+1.5O2N2+3H2O (1. 1st order for both reactants) 3: 2NO+O22NO2 ( 2nd order for NO and 1st order for O2) 4: 4NH3+6NO5N2+6H2O(2/3 order for NH3 and 1st order for NO) The specific reaction rates have been converted to per unit volume basis an are given as: k1NH3=5(m3/kmol)2/min,k2NH3=2m3/kmol.min, there thop 20.1k302=10(m3/kmol)2/min,k4NO=5(m3/kmol)2/3/min Initial Feed rate (NH3)=20dm3/min, Initial Feed rate (O2)=20dm3/min Initial CNH3=COO2=2mol/dm3. Determine molar flow rates of all species as a function of position (i.e., volume) in the reactor. To get full credit, write a mini report which must include: - differential mole balance equations - rate laws and stoichiometry for all reactions - net rates for each species - equations in PolyMath or MATLAB - your PolyMath or MATLAB code Provide solution of all molar flow rates in tabular and graphical form as a function of reactor volume v, from v=0 to v=20dm3. Assume isothermal conditions and pressure drop of 20%
