Latest Patents

Zhaoyang Fei holds a patent for a "Method for preparing amorphous silica-alumina encapsulated metal oxide catalyst and application thereof." This invention discloses a method for preparing an amorphous silica-alumina encapsulated metal oxide catalyst. The catalyst is created by filling silica-alumina precursors in tunnels of a monometallic or bimetallic complex and then performing heat treatment. The advantages of this catalyst include highly dispersed acidic sites and oxygen vacancies, a large pore size range, and high mass transfer efficiency. It significantly improves the efficiency of a cracking-oxidation tandem reaction and achieves full purification of carbon and nitrogen pollutants in landfill leachate. The COD removal rate of the landfill leachate reaches 98.3% or above, while the ammonia nitrogen removal rate reaches 98.0% or above. The COD concentration of the purified effluent is less than 98.7 mg/L, and the ammonia nitrogen concentration is less than 24.9 mg/L.
