Abstract
Abstract Nitrous oxide (N 2 O) is one of six greenhouse gases listed up in the Kyoto Protocol, and it effects a strong global warming because of its much greater global warming potential (GWP), by 310 times over a 100-year time horizon, than CO 2 . Although such N 2 O emissions from both natural and anthropogenic sources occur, the latter can be controlled using suitable abatement technologies, depending on them, to reduce N 2 O below acceptable or feasible levels. This paper has extensively reviewed the anthropogenic N 2 O emission sources and their related compositions, and the state-of-the-art non-catalytic and catalytic technologies of the emissions controls available currently to representative, large N 2 O emission sources, such as adipic acid production plants. Challengeable approaches to this source are discussed to promote establishment of advanced N 2 O emission control technologies. Key Words : Nitrous oxide (N 2 O), Global warming, Anthropogenic sources, Adipic acid, Catalytic emission controls
