CO在稀土复合吸附剂上吸附特性的研究

Study of adsorption characteristics of CO on compound adsorbents with rareearth elements

采用流动重量法测定ＣＯ在稀土复合吸附剂上的吸附平衡和吸附动力学数据，吸附等温线可用Ｌａｎｇ－ｍｕｉｒｅ方程较好的拟合，吸附动力学数据可用单孔扩散模型拟合，得到了吸附热及活化能值并对吸附机理作了探讨。

The data of adsorption equilibrium and adsorption kinetics of CO on compound adsorbents with rareearth elements were measured by a flow gravimetric method. The adsorption isotherms were simulated with the Langmuir equation while the kinetic adsorption data with the monoporous diffusion model. Thus, the values of adsorption heat and activation energy were obtained and the adsorption mechanism was studied. These studies could offer necessary fundamental characteristics for developing film adsorbents and supply a new way of studying CO adsorbents.
