研究正丁烷在挤压圆柱形活性炭颗粒上的吸附，提供两种信息：温度和烃分压对吸附动力学（动力学研究）和吸附容量（热力学研究）的影响。热力学方面可以通过朗缪尔模型来解释。从动力学的角度来看，我们通过实验证明了吸附过程中颗粒内部会发生强烈的温度变化。在本文中，提出了一个包括传质和传热现象的动力学模型。动力学模型预测与碳氢化合物吸附过程中颗粒内部的实验质量和温度变化之间存在良好的一致性。
The adsorption ofn-butane on extruded cylindrical activated carbon grains is studied providing two kinds of information: the influence of the temperature and the hydrocarbon partial pressure on the adsorption dynamics (kinetic study) and on the adsorption capacities (thermodynamic study). The thermodynamic aspect could be interpreted by a Langmuir model. From a kinetic point of view, we have experimentally proved that strong temperature variations occur inside the particles during the adsorption. In this paper, a kinetic model including both mass and heat transfer phenomena is proposed. Good agreement is found between the kinetic model predictions and the experimental mass and temperature variations inside the grain during the hydrocarbon adsorption.
