摘要：

发展沼气产业一定程度上可缓解我国天然气供需矛盾问题，近年来得到广泛关注。要实现与石化天然气的互通互用，沼气需进行脱碳净化处理。本文综述了膜接触器技术在沼气脱碳领域的应用，主要介绍了膜材料、吸收剂、膜组件设计、操作条件与过程模拟等方面的研究进展，并对膜接触器沼气脱碳技术在实际应用中所面临的膜润湿问题进行了探讨。本文对沼气脱碳研究和膜接触器过程开发具有一定的参考价值。

The development of biogas industry can relieve the contradiction between supply and demand of natural gas in China, and it has attracted much attention in recent years. To realize the practical application similar to petrochemical natural gas, the CO2 removal is necessary for biogas before use. In this paper, the application and research progress in CO2 removal from biogas using membrane contactor technology was reviewed. The research status in membrane material, absorbent, design of membrane module, operation conditions and process simulation was mainly summarized. The major challenge of membrane contactor in practical application for CO2 removal from biogas, i.e., membrane wetting, was discussed. This paper provided reference for the CO2 removal and process development of membrane contactor technology.
