Problem 5 (20 pts). Consider this gas-phase second-order reaction: 2AB+C This reaction is carried out isothermally at 260C in a PBR. Givens: entering volumetric flow rate: v0=8m3/h, catalyst pellet size: Dp=0.006m, solid catalyst density: c=2000kg/m3, cross-sectional area: Ac=0.001m2, pressure-drop parameter: 0=10kPa/m, reactor length: z=L=20m,=0.5,P0=1000kPa,CA0=0.1kmol/m3, and k=12m6/kmol.kg-cat.h (a) Calculate the conversion in the absence of pressure drop (10 pts). (b) Calculate the conversion in the presence of pressure drop (10 pts)
