从FCC装置再生器中排出的因燃烧产生的污染物主要有CO，SOx和NOx，前两种都可通过催化方法，如使用助燃剂和硫转移添加利控制其排放量。但是，控制NOx排放量的技术难度较大，直到最近，GraceDavison公司才开发出控制N民排放量的催化方法。G。ceDavison公司的研究表明，催化剂焦 The emissions from the FCC unit regenerators are mainly CO, SOx and NOx due to combustion, the first two being controlled by catalytic processes such as the use of oxidizers and sulfur transfer additives. However, it is more difficult to control NOx emissions and, until recently, Grace Davison developed a catalytic approach to controlling N emissions. G. Ce Davison’s research shows that the catalyst coke
