摘要
N2O是一种温室效应很强的氮氧化物气体,对臭氧层能产生较大的破坏作用。介绍了温室气体N2O的排放和危害、生物质再燃脱除N2O技术的研究现状,分析了再燃温度、再燃比、过量空气系数、停留时间等因素的变化对N2O还原分解的影响,并讨论了目前N2O减排的主要方法,其中利用生物质气化气催化还原是今后N2O减排的主要发展方向。
As a powerful greenhouse gas,N2Ohas serious destruction on ozone layer. Emissions and harms of N2O were introduced. The N2O removal technology by biomass reburning were discussed through analyzing the effect of reburning temperature, reburning fuel ratio, excess air coefficient, residence time onN2O decomposition. Mainly there are four kind methods to achieve N2O decomposition and reduction, in which catalyze and reduction during the process of biomass gasification gas reburning on N2O was the most promising technology.
