Hydrogen peroxide catalyst

basic information

Numbers:

HP-S3

Detailed

HP-S3 Hydrogen peroxide catalyst

Application： the catlayst is Widely used in the process of hydrogen peroxide production, anthraquinone hydrogenation and desulfurization, acetylene removal in olefin, gas deoxidation and other chemical industry, medicine, environmental protection fields.

Characteristics：
1.Large pore volume, high activity, good stability, long life.

Molding with oil column method, the catalyst has the characteristics good pore structure , large pore volume, large specific surface, Aperture concentration and high strength, Its activity is higher 20-40% than other catalysts. Because of high activity and stable precious metal components, it is not easy to depalladium and good stability. The catalyst has long service life (generally more than 5 years).

2.Strong acid and alkali resistance, fatigue resistance, good water and thermal stability

Because the carrier preparation process is oil column method by oil surface tension molding, non-extrusion, rolling and other external forces forming, the carrier has stable structure, excellent structural characteristics and strong acid and alkali resistance and fatigue resistance, good water and thermal stability.

3.Stable batch quality, high yield, less impurities

The direct raw material of oil column molding is liquid gel. The molding depends on the effect of surface tension and specific gravity differences and falls into the sphere,the spheres are uniform size and convenient operation.
