8.b) It has been observed that 60% conversion of reactant A is achieved during its hydrogenation in a 4m3 slurry reactor using 5kg/m3 loading of 60m spherical catalyst. If the inlet molar flow rate of reactant A is 0.7kmol/min, value of rsr is 0.21minkg/m3 and the interfacial concentration of hydrogen is 0.014kmol/m3, determine the value of bubble to liquid phase mass transfer resistance, rb. If the overall reaction is internal mass transfer controlled, do you expect any change in the catalyst loading if the stirring rate is doubled? [4]
