摘要： The NOx content of FCC regenerator flue gas is reduced using a spinel/perovskite additive which maintains activity during FCC operation in the presence of high levels of sulfur oxides and oxygen. Additionally, a stabilization component may be added to enhance catalytic stability of the additive, and a cracking component may be added under conditions of low reducing agents in the regenerator flue gas.
