✦ Synopsis

The adsorption and desorption behaviour of several gases on Na-Y and Cu(ll)-Y zeolites was investigated by flow calorimetry. The temperature change observed in the adsoprtion and/or desorption of the gases with a twin conduction calorimeter was treated with an adequate computation circuit. The temperature vs. time curve formed in this way was such as could have been obtained in a perfectly adiabatic process. The rate of adsorption and desorption was determined by differentiating the temperature vs. time curves with respect to time. The heat of adsorption of CO on Cu(II)-Y and that of CO2 on Na-Y were found to agree well with earlier data.
