摘　　要：以餐厨垃圾生产的沼气为例,介绍沼气净化提纯的工艺流程,阐述变压吸附(PSA)脱碳技术的原理、工艺流程、吸附剂的选用、工艺特点,膜分离脱碳技术的原理、工艺流程、膜分离材料的特点、工艺特点,对变压吸附脱碳技术和膜分离脱碳技术进行比较,变压吸附脱碳技术具有优势。Taking biogas produced from kitchen waste for example, the process flow of biogas purification is introduced. The principle, process flow, selec- tion of adsorbent and process characteristics of decar- bonization technology by pressure swing adsorption （PSA） as well as the principle, process flow, characteristics of membrane separation material and process characteristics of decarbonization technology by membrane separation are elaborated. The decarbonization technology by PSA is compared with the decarbonization technology by membrane separation, and the for- mer has more advantages.
