选择性催化还原法（Selective Catalytic Reduction，SCR）是指在催化剂的作用下，利用还原剂（如NH3、液氨、尿素）来“有选择性”地与烟气中的NOx反应并生成无毒无污染的N2和H2O。

2023年1月1日 · It summarizes the modified methods for SCR performance to meet the increasingly stringent NO x emission requirements, such as the second metal, replacement of support, formation of special structures, post-treatment. The NO x conversion, N 2 selectivity, SO 2 resistance and hydrothermal stability of the catalyst are also reviewed.

2019年8月15日 · Selective catalytic reduction with NH 3 (NH 3 –SCR) is the most efficient technology to reduce the emission of nitrogen oxides (NO x) from coal-fired industries, diesel engines, etc.

2025年2月1日 · The selective catalytic reduction (SCR) of NO x, utilizing carbon monoxide (CO) and ammonia (NH 3), is recognized as an effective approach for NO x abatement. During the SCR process, the appropriate pretreatment of catalysts can significantly enhance their surface and interfacial structures, thereby improving their activity, selectivity, and ...

5 天之前 · Selective catalytic reduction with NH3 (NH3-SCR) is an important means of NOx abatement from stationary and mobile sources, and the key element is eff…

4 天之前 · To elucidate the promotional effect and underlying mechanisms of sulfur doping on the NH3-SCR performance of CeO2 catalysts, a detailed study of sulfated CeO2 catalysts was conducted. The CeOxS0.1 catalyst, with modest sulfur doping, outperforms its pure CeO2 counterpart, achieving over 90% NOx conversion and above 98% N2 selectivity within the temperature range of 230–480 °C. The enhanced ...

2024年4月22日 · 该研究发现为Cu-SSZ-13等Cu基小孔分子筛催化剂上的NH3-SCR反应过程提供了新的认识，并为进一步优化改进分子筛催化剂的脱硝性能指明了可行方向。

2024年10月30日 · There are two terminal techniques for NO x removal in waste incineration: non-selective catalytic reduction (SNCR) and selective catalytic reduction (SCR). SNCR is used to remove NO x with no catalyst and sprays ammonia or urea into the incinerator at 850–1050 °C.

This paper reviews the active components, carriers, synthesis methods and the factors affecting the catalytic performance (activity and stability) of low-temperature selective catalytic reduction denitrification catalysts.
