摘要(Abstract)：

以烧结矿为催化剂对烧结烟气进行选择性催化还原(SCR)脱硝,研究了反应温度、NH3/NO物质的量比、空速和烧结矿粒径对烧结烟气SCR脱硝的影响。结果表明:烧结矿催化还原烧结烟气脱硝效果明显;烧结矿SCR脱硝的适宜窗口温度为350⁴50℃;随NH3/NO物质的量比增大、烧结矿粒径减小、空速(气体流速/催化剂体积)降低,脱硝效率提高;在反应温度为450℃、NH3/NO物质的量比为1.0、空速为3 000 h-1的条件下,用粒径为0.2450℃;随NH3/NO物质的量比增大、烧结矿粒径减小、空速(气体流速/催化剂体积)降低,脱硝效率提高;在反应温度为450℃、NH3/NO物质的量比为1.0、空速为3 000 h-1的条件下,用粒径为0.2¹.0 mm的烧结矿脱除烧结烟气中的NO,可以将NO质量浓度从400 mg/m3降到约260 mg/m3。
