| Product description: Environmentally-friendly FCC cocatalyst (reduce emission)
Chemical composition: compounded oxides of ⅡA/ⅠB group and rare earth elements.
Three types of products in this series: J/DNS (serves to remove nitrogen sulfur oxide), J/DN (serves to remove nitrogen oxide) and J/DS (serve to remove sulfur oxide). They can also increase liquid recovery.

Instruction
Feed this cocatalyst to the unit through combustion improver inlet or mixed it with FCC catalysts. The volume
weights around 2%-3% of the catalyst inventory, thereafter, add cocatalyst about 2-3% of attrition loss of FCC every day.
