3. From Example 8-1 (Essentials of Chemical Reaction Engineering), Consider the following system of gasphase reactions: AXrx=K1CA1/2k1=0.004(mol/dm3)3/2min1ABrB=k2CA1/2k2=0.3min1AYrY=k3CA2k3=0.25dm3/mol.min (a) Sketch the instantaneous selectivities (SB/X,SB/Y, and SB/XY= rB/(rx+ry)) as a function of the concentration of CA. (b) Consider a series of reactors. What should be the volume of the first reactor? (c) What are the effluent concentrations of A,B,X, and Y from the first reactor? B is the desired product, and X and Y are foul pollutants that are expensive to get rid of. The specific reaction rates are at 27C. The reaction system is to be operated at 27C and 4 atm. Pure A enters the system at a volumetric flow rate of 10 dm3/min What is the conversion of A in the first reactor? If 99% conversion of A is desired, what reaction scheme and reactor sizes should you use to maximize SB/RX? Suppose that E1=20,000cal/mol,E2= 10,000cal/mol, and E3=30,000 cal/mol. What temperature would you recommend for a single CSTR with a space time of 10min and an entering concentration of A of 0.1 mol/dm32
