| 摘 要： | 本文介绍了一套吸附热测定装置, 它是对法国SETARAM高温量热计进行了适当变动后而建成的。用它可以测定在室温～800 K范围内气/固吸附的微分吸附热。在实验过程中, 吸附量是用光标微压计进行测量。用电标定法代替标准物质法来测定该装置的热定量因子, 这更适合于在恒温条件下的吸附热测定。用这套装置测定了吡啶在HY分子筛上于不同温度下的吸附热。

| Abstract: | 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. |
