部分燃气内燃机烟气排放NOx浓度可高达2000~5000mg/Nm 3 ，而燃气内燃机烟气排放NOx的要求日趋严格。2018年，优美科公司采用专用于燃气内燃机烟气SCR脱硝的DNX-GT催化剂及“双SCR反应器”技术，为内蒙古明拓铬业公司成功实现NOx自2000mg/Nm 3 至75mg/Nm 3 ，同时氨逃逸小于 ...

结合220t/h煤粉锅炉烟气SCR脱硝工程实例，详细阐述了氨水贮存及输送系统、氨水蒸发系统、SCR反应器等工艺流程及相关设备选型选材，分析了系统运行效果及其经济性。结果表明，SCR反应器进口NOx质量浓度为782～796 mg / Nm3，NH3/ NOx摩尔比为0. 93时，出口可降至71 ...

Optimal NO x removal by a selective catalytic reduction (SCR) system requires the inlet gas temperature to remain within a prescribed range. How does a baseload unit ...

选择性催化还原（NH3-SCR）技术可有效处理氨氢发动机尾气中的NOx污染。本研究基于密度泛函理论（DFT），系统揭示了单原子Fe负载β分子筛的NH3-快SCR吸附特性与反应机制。通过分析7条可能的反应路径，证实路径5为主流反应路径，路径4因能量垒过高不利进行。

本文系统研究了不同骨架结构（CHA、MOR、beta）的Cu/Fe–分子筛催化剂在NH3–SCR（选择性催化还原）反应中的性能，发现串联层 ...

For nearly five years, two selective catalytic reduction (SCR) systems have operated almost around the clock at Dynegy Midwest Generation’s Baldwin Energy Complex in Baldwin, Ill. The SCR systems ...
