摘要： 采用机械混合法制备了Li2O-CaO吸附剂，在固定床管式反应器中研究了Li2O-CaO吸附剂的吸附性能，考察了吸附温度、空速及吸附剂粒径对静吸附容量的影响，确定了适宜的工艺条件，采用XRD和SEM对改进的钙基吸附剂进行了表征。结果表明，Li2O-CaO吸附剂对CO2有较好的吸附能力，在吸附温度600 ℃、空速8 min－1、吸附剂粒径60～80目（0.18～0.28 mm）的条件下，静吸附容量达到了17.3891 mol/kg。

Abstract: The Li2O-CaO absorbent was prepared by mechanical blending method. The performance of Li2O-CaO absorbent was tested in a fixed bed tubular reactor，and the influences of adsorption temperature，space velocity，and adsorbent particle size on the static adsorption capacity were investigated. The suitable reaction condition was determined，and the modified calcium-based adsorbent were characterized by techniques such as XRD and SEM. Results indicated that the Li2O-CaO absorbent has good adsorption ability for the CO2，and the static adsorption capacity amount to 17.3891mol/kg under the condition of adsorption temperature 600oC，space velocity 8min－1and adsorbent particle size 60—80 bean size（0.18—0.28 mm）.

Key words: lithium oxide, calcium-based adsorbent, carbon dioxide（CO2）, high temperature
