The Catalytic Additives For The Reduction Of NOx In FCC Regenerated Flue Gas
1,Application
Reducing FCC regenerator flue gas NOx content, ease the regeneration system of corrosion problems, solution regenerator" nitrate embrittlement problems".
2,Product performance
It can effectively reduce the FCC regenerator flue gas NOx content, while alleviating regeneration corrosive problem of the system, lowering the dew point of the flue gas temperature.
With the CO combustion-supporting function, can replace widely used platinum-based combustion-supporting agent.
It does not cause other pollutant emissions increase.
3,Range of application
It can be used to the nitrogen containing gas oil catalytic cracking and blending the residue and the residue of heavy oil catalytic cracking unit.

5,Instruction
Industry through the combustion-supporting agent feeding tank and small feed pipe auxiliary agent is added to the regenerator beds, additive method using a join and a normal complement. Usually fast join and balance to join two stage. According to the regenerator flue gas NOx content and content of catalyst in the consumption of fast, join, to be regenerated flue gas NOx is reduced to a level, to balance the joining phase. Add agent at the same time, device stop combustion improver. System builder should maintain a certain concentration ( generally accounted for reaction-reproduction system reservoir capacity of 1 ~ 5%). Use effect to add agent before and after regeneration flue gas changes in NOx content evaluation.
6,Storage
This product is used in plastic woven bags, bags of 25 kg net each. In a cool ventilated place storage. The shelf-life is 18 months.
