The required energy of the global industry is mostly generated from fossil fuel sources, such as natural gas, gasoline, diesel, oil, and coal. Nitrogen oxides are one of the main air pollutants that are produced from the combustion of fossil fuels in stationary and mobile sources. Development of new technologies to decrease the NOx emission from exhaust gases is essential due to the harmful effect of NOx on the environment and human health. Compared with pre-combustion and combustion methods (with <50% NOx removal efficiency), the post-combustion methods with higher efficiency (above 80%) have attracted more attention in NOx elimination. This review describes the currently used technologies of NOx abatement. Different available post-combustion methods of NOx removal, including selective catalytic reduction (using different types of reducing reagents, including ammonia, hydrogen, hydrocarbons, and carbon monoxide), selective noncatalytic reduction, wet scrubbing, adsorption, electron beam, nonthermal plasma, and electrochemical reduction of NOx, are discussed.

烟气中的氮氧化物还原技术：综述。

全球工业所需的能源主要来自化石燃料，例如天然气，汽油，柴油，石油和煤炭。氮氧化物是固定和移动源中化石燃料燃烧产生的主要空气污染物之一。由于NOx对环境和人体健康的有害影响，因此开发减少废气中NOx排放的新技术至关重要。与预燃烧和燃烧方法（NOx去除效率<50％）相比，效率更高（80％以上）的后燃烧方法在消除NOx方面引起了更多关注。这篇评论描述了目前使用的NOx减排技术。燃烧后的各种不同的NOx去除方法
