Abstract

ABSTRACT It is crucial to control NOx emission into the atmosphere because it can make several harmful health and environmental effects. Many techniques are available for NOx reduction, and among them, selective catalytic reduction (SCR) is one of the most efficient techniques for NOx removal in flue gas cleaning process. The reduction of NOx by CO offers a simple and low-cost technology for reducing NOx emissions from mobile or stationary sources. In this review, NOx emission, different NOx control technologies, and the challenges for the SCR process are studied. This paper reviews various types of catalysts, including supported and unsupported metal oxide catalysts as efficient catalysts for NOx reduction by CO. The reported experimental researches are analyzed to make an overview of the NOx reduction through CO-SCR process. Moreover, catalytic performances in the presence of oxygen, water steam, and sulfur dioxide, which usually exist in exhaust gases produced in the combustion process, are discussed. Moreover, this paper reviews the possible reaction mechanisms for the CO–SCR.
烟气净化过程中一氧化碳选择性催化还原NOx的研究进展
摘要氮氧化物排放对人体健康和环境具有多种危害,控制氮氧化物排放至关重要。NOx的还原技术有很多,其中选择性催化还原(selective catalytic reduction, SCR)是烟气净化过程中最有效的NOx脱除技术之一。一氧化碳减少氮氧化物为减少移动或固定源的氮氧化物排放提供了一种简单而低成本的技术。本文对SCR工艺的NOx排放、不同的NOx控制技术以及面临的挑战进行了研究。本文综述了各种类型的催化剂,包括负载型和非负载型金属氧化物催化剂作为CO还原NOx的有效催化剂,并对已有的实验研究进行了分析,概述了CO- scr工艺还原NOx的研究概况。此外,讨论了在氧气、水蒸气和二氧化硫存在下的催化性能,这些通常存在于燃烧过程中产生的废气中。此外,本文还对CO-SCR可能的反应机理进行了综述。
