Abstract
The transport behaviour of carrier gases with inorganic catalytic ceramic membrane used for ethyl lactate production and VOC (volatile organic compound) recovery in the gauge pressure range of 0.10-1.00 bar and temperature range of 333 K was investigated. The gases include Ar (argon), N2 (nitrogen) and CO2 (carbon dioxide). The gas kinetic diameter with respect to permenace was found to occur in the order of Ar > CO2 > N2, which was not in agreement with molecular sieving mechanism of transport after the first dip-coating of the support. However, gas flow rate was found to increase with gauge pressure in the order of Ar > CO2 > N2, indicating Knudsen mechanism of transport. The porous ceramic support showed a higher flux indicating Knudsen transport. The surface image of the dip-coated porous ceramic membrane was characterised using SEM (scanning electron microscopy) to determine the surface morphology of the porous support at 333 K.
