  • Publication number: 20210178370
    Abstract: A modified Y-type molecular sieve has a rare earth content of about 4% to about 11% by weight on the basis of the oxide, a phosphorus content of about 0.05% to about 10% by weight on the basis of P2O5, a sodium content of no more than about 0.5% by weight on the basis of sodium oxide, and an active element content of about 0.1% to about 5% by weight on the basis of the oxide, with the active element being gallium and/or boron. The modified Y-type molecular sieve has a total pore volume of about 0.36 mL/g to about 0.48 mL/g, a percentage of the pore volume of secondary pores having a pore size of 2-100 nm of about 20% to about 40%; a lattice constant of about 2.440 nm to about 2.455 nm, and a lattice collapse temperature of not lower than about 1060° C.

  • Publication number: 20200129964
    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.
