Molecular sieve catalyst for supercritical catalytic oxidation of high-concentration organic wastewater
A molecular sieve catalyst for supercritical catalytic oxidation of high-concentration organic wastewater adopts a silicon-aluminum molecular sieve (SiO2/Al2O3 > 100) as a catalyst carrier, utilizes a huge specific surface area given by a molecular sieve porous structure, and adopts impregnated and sintered rare earth elements to modify the carrier, so that the stability of the carrier is improved. Multi-element oxide V2O5: WO3: TiO2 is adopted as an active component, and the multi-element oxide and a carrier modification element form a high-entropy oxide with more than five elements, so that the stability of the active component is improved, the dissolution rate of the active component is reduced, the use durability of the catalyst is improved, and the structure of the catalyst is further strengthened. The catalyst has the advantages of simplicity and convenience in process operation, abundant and easily available raw materials, high catalytic efficiency, high catalyst durability, great improvement of the catalytic efficiency, reduction of the catalytic conditions, and very high industrial application prospects.
