摘　　要：随着国内沼气产业的迅速发展,如何高值化利用沼气、发挥更大经济效益是大中型沼气工程由环保型模式向能源型模式转变的关键。目前,国内外沼气利用方式已呈现由驱动发电机进行热电联产向净化提纯制取生物甲烷转变。生物甲烷用于替代石化天然气或用作车用燃气,是沼气高值化、能源化利用的重要发展方向。该文概述了国内外沼气净化提纯技术及产业发展现状,阐述了目前沼气脱除硫化氢、二氧化碳的工艺技术研究状况和进展。With the fast development of biogas industry in China,how to use the biogas to achieve greater economic benefits is one of key factors affecting development model shift of middle and large scale biogas plants from environment protection mode to energy generation mode.The usage of biogas is changing from fueling combined heat and power generator engines to upgrading biogas to bio-methane.Biogas purification and upgrading is one of the high value applications of biogas.Bio-methane can be used as compressed natural gas and vehicle fuel.This paper summarizes the development of biogas purification industry at home and abroad.The technologies for removal of hydrogen sulfide and carbon dioxide are also reviewed.
