FCC过程中NOx形成机理及其脱除技术

THE MECHANISM OF NO_x FORMATION IN FCC PROCESS AND THE DENO_x TECHNIQUES

摘要: 介绍了催化裂化过程中生成热NOx，燃料型NOx和快速型NOx的形成机理，以及各种脱除催化裂化再生烟气中氮氧化物的方法，如：两段再生器、脱NOx助剂、改进的CO助燃剂等等，并对这些方法进行了讨论和分析。

Abstract: The formation mechanism of thermal NOx, fuel NOx and prompt NOx in FCC process were introduced. The methods that deal with the NOx problem were discussed, such as the two - stage regenerator, the deNOx additives and the modified CO combustion promoter.
