摘要
对天然气再燃过程中添加的有机酸盐同时脱硫、脱氮反应途径及机理进行了详细的分析。探讨了有机酸盐(钙镁醋酸盐CMA)分解的CHi还原NO的主要机理,研究了CMA固硫的反应机理,分析了脱硫过程影响HCN、NH3还原NO的因素。提出了天然气再燃添加CMA同时脱硫、脱氮时,也要综合考虑CaO对SO2的脱除和对NO生成的促进作用。
The reaction mechanism of simultaneous reduction of NOx and SO2 from natural gas reburning by injection calcium magnesium acetate was introduced in detail. The main reduction reaction mechanism of CH which was decomposed from organic acid salt（ calcium magnesium acetate CMA）with NO was discussed, The CMA desulfurization mechanism was researched and the factors affected HCN、NH, reduction NO during desulfurization were also analyzed. The acceleration function of CaO must be comprehensive considered when the additive CMA was used to the simultaneous removal of NOx and SO2 from natural gas reburning.
