Abstract: The nitrogen chemistry during the regeneration of coked fluid catalytic cracking (FCC) catalyst is reviewed，including the main types and formation pathways of the nitrogen compounds on the coked FCC catalyst，the transformation pathways of these nitrogen compounds and nitrogen intermediates during the regeneration process. Strategies to control the NO_x emission from FCC regenerator are also discussed.
