Title:
ANTI-METAL LIQUID YIELD BOOSTER FOR CATALYTIC CRACKING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/017456
Kind Code:
A1
Abstract:
Provided are an anti-metal liquid yield booster for catalytic cracking and a preparation method therefor. The liquid yield booster is composed of a VPI-5 molecular sieve, and an antimony-based nickel passivator and a heteropoly acid together loaded in a pore channel thereof, wherein the mass fractions of the components are: 70-98% of a VPI-5 molecular sieve; 0.5-20% of an antimony-based nickel passivator; and 1-10% of heteropoly acid. With the anti-metal liquid yield booster of the present invention, a nickel-porphyrin compound can be concentrated in the pore channel of the VPI-5 for a cracking reaction, and the resulting metal nickel is controlled to remain in the pore channel of the VPI-5, such that the toxicity thereof to a catalytic cracking catalyst is reduced, and furthermore, the nickel element is more quickly exposed and reacted with the nickel passivator, and this is favorable for improving the reaction selectivity and reducing the generation of coke, and there is increased production of liquid products such as gasoline and diesel oil.
