| 摘 要： | 沼气中主要含CH4和CO2,还有少量的H2S,NH3,痕量的H2,N2,O2,CO和卤化烃,沼气通过净化达到含甲烷97%以上,可以被用作汽车燃料,并入天然气网,沼气燃料电池发电等高端应用,发挥更大的经济价值。本文综述了近年来国外在沼气应用方面的主要技术状况和进展,并结合我国沼气应用方式现状分析了我国沼气能源应用的发展方向。

| Abstract: | Biogas is primarily composed of methane(CH4) and carbon dioxide(CO2) with small amounts of hydrogen sulphide(H2S) and ammonia(NH3),and trace amounts of hydrogen(H2),nitrogen(N2),carbon monoxide(CO),halogenated carbohydrates.Biogas could be used as fuel for vehicle or fuel cell,or merging into nature gas net after purification when the methane content reached to 97%,The biogas purification and application technology in recent years were reviewed in this paper,and developing orientation in our country were analyzed and suggested. |
