Hydrogen peroxide catalyst
Classification:
Product name:

Hydrogen peroxide catalyst

Numbers:
HP-S3
Detailed

Product characteristics:

1.Large pore volume、high activity、good stability、long application life

The product which uses oil column forming method has good pore structure and advantages like large pore volume、large specific surface、concentrated pore diameter and high strength. The activity is 20-40% higher than other catalysts. It is difficult to de-palladium and has good stability、long application life(generally more than five years) because of the high activity and stable precious metal components.

2. Strong acid & alkali resistance、fatigue resistance、hydrothermal stability

Since the carrier fabrication process is oil column forming method which relies on the oil surface tension one-time molding without external forces like extrusion and rolling, the structure is stable and the carrier has good structural characteristics、strong acid & alkali resistance、fatigue resistance and good hydrothermal stability.

3. Stable batch quality、high finished product yield、few impurity

The direct material of oil column forming method is liquid gelatin, and the spherical molding relies on the oil surface tension and specific gravity which is easy to operate and makes the catalyst uniform in size; the product use high specification raw materials to guarantee the few impurity

Product Technology:

It uses high-purity aluminum as the aluminum source to produce alumina sol, add gelling agent to produce gelatin, uses oil column forming method, get spherical active aluminum oxide carrier via sublimation、drying、roasting which has features such as stable structure、large pore volume、high strength and high activity. Then catalyst can be made by adding palladium into carrier. Its shape is spherical or near-spherical.

Production Scale: 200t/year

Product Usage:

It is widely used in catalytic hydrogenation、absorptive removal fields of chemical industry、medical industry、environmental protection, such as anthraquinone hydrogenation in the hydrogen peroxide production、desulfurization、olefin de-acetylene、gas de-oxy purification.
