9、alyst Reduction SCR - 选择性催化还原法 Selective Catalytic Reduction (SCR) is a post-combustion control technology based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H2O)。 选择性催化还原法是基于NOx化学还原成分子N2和水蒸气H2O的燃烧后控制技术。 SCR technology was firstly developed by Amer
10、ican in 1950s and patented by Eegelhard company in 1957. The first industrial scale application was in Japan in the end of 1970s. SCR技术最早是在上世纪五十年代美国人首先提出的，美国Eegelhard公司于1957年 申请了该技术的发明专利。七十年代末最早在日本实现工业规模的应用。 SCR is the most widely used, the most developed and effective DeNOx technology in the world.
11、 SCR是世界上应用最广泛，最成熟和最有效的的脱硝技术。NOx Formation NOx的形成机理的形成机理 There are three mechanisms of NOxformation.
