An adsorption column is packed with an adsorbent that has an adsorption area of 1500m².⁻¹. The packed voidage is 40% and the bulk density of the adsorbent is 400*m⁻³. Assume the pores are all cylindrical with an average pore diameter of 1.6m .
Determine the porosity of the adsorbent. [4] The same adsorbent is now used to adsorb a component with a concentration of 100m . -1 from a fermentation broth. The fermentation broth is pumped at 4m³. ℎ⁻¹ to the adsorption column. The isotherm that described the equilibrium adsorption is given by: where = adsorbed per adsorbent = concentration of solute ( /)
