    Product performance

    After high temperature calcination, the quality is extremely hard, but it has a special specific surface area, pore volume and pore size. It can eliminate the diffusion effect in the gap. In the process for selective oxidation, it can reduce the side reactions of deep oxidation, and can form a special shell structure during the impregnation process, which effectively improves the reaction performance.

    Application area

    Silver catalyst support, precious metal catalyst support for the oxidation of ethylene to ethylene oxide, and special catalyst support in the chemical industry.
