Latest Patents

One of his latest patents is titled "Monolithic catalyst used for carbon dioxide hydrogenation reaction and method for preparing same." This invention involves a monolithic catalyst that comprises a honeycomb ceramic carrier, a coating, and active components. The unique design allows for the separate application of the coating and active components to the honeycomb ceramic hole walls. Each hole is divided into upper and lower segments, with different active components loaded onto each segment. The preparation method includes applying a coating through impregnation and subsequently adding active components to create the final catalyst.

Another significant patent is the "Vanadium-based catalyst and preparation method therefor." This catalyst features an active phase carried on a carrier, which includes vanadium oxide, potassium sulfate, sodium sulfate, and various assistants. The carrier is made of ultra-large-pore silicon dioxide and diatomite, with specific pore size requirements. The preparation method involves a series of steps, including mixing potassium vanadium with potassium hydroxide and conducting a neutralization reaction, followed by rolling, band extrusion, drying, and roasting to produce the catalyst.
