Environmentally friendly FCC catalyst for reducing sulfur, nitrogen, and PM2.5 emissions from flue gas
fcc@fcccatalyst.net
It is an environmentally friendly FCC catalyst that we have successfully developed to reduce SO2, NOx and PM2.5 emissions in flue gas. This catalyst has a sulfur transfer agent component and a de-stocking catalyst component during the manufacturing process, which can remove sulfide in the flue gas. Reduce by half and transfer to dry gas to produce sulfur, which can reduce the pressure of flue gas desulfurization, reduce the use of caustic soda by 50% and the emissions of sodium sulfite by 50%; meanwhile, reduce the emission of nitrogen oxides in flue gas by more than 30% , Reduce the subsequent denitration pressure and reduce the consumption of ammonia.
At the same time, the catalyst also has the advantages of low fine powder content and high strength. The fine powder content of 0-20 microns is less than 1%, the fine powder content of 0-40 microns is less than 7%, and the wear index of the catalyst is less than 1. PM2.5 and other dust emissions are extremely low, which is more than half that of ordinary FCC catalysts.
At the same time, the catalyst has the characteristics of high activity and high rare earth content, good selectivity of gasoline and propylene, high yield, low yield of diesel and oil slurry, and significantly improved economic benefits of catalytic cracking plant products. The light oil yield of the catalyst was increased by more than 1%. This is widely used in various catalytic cracking and catalytic cracking devices. It has been used by domestic and foreign manufacturers, and its customers include petrochemical companies in the United States, the Middle East, Southeast Asia and other countries. The company can specifically design and produce suitable catalysts for each refinery according to the types of equipment, raw material types and product requirements of each refinery, so as to achieve one plant and one agent in order to achieve the best economic benefits.
