The unit consists of a single stainless steel adsorption column of a 2.15 cm I.D. and a 50 cm length. The top and the bottom of the adsorption column were plugged with glass wool. Three thermocouples were installed at 12.5, 25.0 and 37.5 cm from the feed section of the column since temperature variation was expected under the non-isothermal conditions resulting from the heat of adsorption.
