Acetone vapor in a nitrogen stream is removed by adsorption in a fixed bed of activated carbon. At a location in the bed where the pressure is 136 kPa, the bulk gas temperature is 297 K, and the bulk mole fraction of acetone is 0.05, estimate the external gas-to-particle mass-transfer coefficient for acetone and the external particle-togas heat-transfer coefficient. Additional data are as follows: Average particle diameter=0.0040 m, and gas superficial molar velocity= 0.00352 kmol/m2 -s.
