摘要
论述了FCC再生烟气中SO_3的生成机理、影响因素以及所带来的危害;提出了降低FCC再生烟气中SO_3含量的应对措施:降低再生主风量、减少铂基CO助燃剂的使用量、使用硫转移助剂和金属钝化剂以及适当增加催化剂的卸剂量。
The formation mechanisms of SO3 in FCC flue gas, the impact factor and associated hazards are described. The effective measures to reduce SO3 in FCC flue gas are proposed, such as reducing regenerator main air flowrate, lowering the dosage of Pt-based CO combustion promoter, applying sulfur transfer catalyst and metal passivator and properly increasing unloading rate of catalysts.
