Abstract
The present invention relates to the field of catalytic cracking, and discloses a composition capable of reducing CO and NOx emissions, the preparation method and use thereof, and a fluidized catalytic cracking method. The inventive composition capable of reducing CO and NOx emissions comprises an inorganic oxide carrier, and a first metal element, optionally a second metal element, optionally a third metal element and optionally a fourth metal element supported on the inorganic oxide carrier, wherein the first metal element includes Fe and Co, and wherein the weight ratio of Fe to Co is 1:(0.1-10) on an oxide basis. The inventive composition has better hydrothermal stability and higher activity of reducing CO and NOx emissions in the flue gas from the regeneration.
