常温条件下赤泥同时脱硫脱硝实验研究
Experimental study on simultaneous desulfurization and denitrification of red mud at low temperature
摘要
Abstract
A fixed-bed reactor was used to study the simultaneous desulfurization and denitrification of red mud at 110℃,as well as the effects of water vapor concentration and SO2 to NO ratio.The physical properties and chemical composition of red mud were measured by BET(Brunauer Emmet Teller)surface area and porosity analyzer,pH meter,laser particle size analyzer(LDSA)and ICP(inductivity coupled plasma mass spectrometry).The experimental results showed that the denitrification efficiency of red mud was 2.4 times that of Ca(OH)2.The effect of NO content in the reaction gas on the removal of SO2 was less than 15％.When the SO2 to NO ratio approached 5,the removal efficiency of NO nearly approached 100％.The optimal range for the effect of water vapor was around 10％.When the water vapor concentration was too high,the conversion and removal of NO can be affected in the early stage,while the desulfurization and denitrification in the later stage were promoted.The effective components for desulfurization and denitrification in red mud mainly included alkaline components and metal oxides.关键词
