QUESTION Answer BOTH parts a and b
A reaction takes place in a porous spherical catalyst particle with radius and effective diffusivity, The concentration of the reactant outside the particle is The reaction exhibits saturation kinetics and the rate equation is:
a Calculate the effectiveness factor of the catalyst particles under the condition of strong pore diffusion resistance.
b The catalyst particles are packed into a multitubular column for chemical adsorption of reactant The molar flow rate and concentration of in the feed are and respectively. Calculate the number of packed tubes required to achieve conversion of The effectiveness factor mav be assumed constant and equal to the value obtained in a
