In this paper, high temperature calorimeter which is France SETARAM has been modified and introduced, Differential heats of adsorption for gas/solid system over the temperature range from ambient temperature to 800 K could be carried out in this apparatus, In the experimental procedure the amount of adsorption for gas or vapour could be measured by a light-spot microbarometer. The conversion factors for the apparatus have been determined through a electric-heating me- thod instead of standard materials which are usually used in temperature program process. By using this apparatus the heat of adsorption for pyrodine on H-Y zeolite at different temperatures have been measured.
