摘要: Abstract The kinetics of water adsorption from an air stream on porous alumina is studied experimentally in a differential bed at five temperatures the range 9·8–64·0°C. mass transfer rate calculated theoretically by means model, which considers simultaneous resistance to pore system solid and film surrounding particle. equilibrium described non-linear Freundlich isotherm. Comparison experiments with theory shows that model describes adequately allows effective diffusivity be calculated. This leads result decreased factor 3 when temperature increased
