Faced with increasingly stringent environmental regulations for the control of combustion gases emissions control, many refineries seek catalytic strategies to reduce NOx emissions.
For FCC units employing Pt-based combustion promoter, its replacement by ELIMINOx™ can be the first step for reducing NOx emissions, aiding the refiner in attaining his environmental compliance goals. .
The Fábrica Carioca de Catalisadores S.A. and Ketjen ELIMINOx™ is a platinum-free combustion promoter able to promote efficient CO to CO2 oxidation, attenuating the CO afterburn phenomenon in the regenerator diluted phase without augmenting NOx emissions when compared with the platinum-based conventional promoters.
Its efficiency has already been commercially proven in more than 20 refineries all over the world, it being a reliable, flexible and low-cost solution. Typically, the NOx levels by using ELIMINOx™ are 40 to 70% lower than those observed for a conventional platinum-based promoter.
