Alumina catalyst carrier extruded catalyst carriers gamma alumina catalyst carrier and alpha alumina catalyst carrier catalyst support

γ-alumina α-alumina catalyst carrier support

What are the raw materials for the catalyst carrier?

Diatomite
Activated carton
Silica gel
Activated alumina
Gamma Alumina
Alpha alumina
Pseudoboehmite powder
SiC
TiO2
Zeolite Molecular sieve( zsm-5 beta zeolite Y zeolite ssz-13 zeolite etc.)
and so on

We produce various extruded carriers including solid extrudates, hollow extrudates, trifolium extrudates, quadrifoil extrudates, papilionaceous extrudates etc. Alumina is the common raw material of this carrier. The main physical properties are as following:

Bulk density: 0.45－0.8 g/cm3；

Pore volume: 0.5－0.8 cm3/g；

Specific surface area: 150－350 m2/g.

Catalyst carrier sphere

The sphere carriers are mainly alumina and magnesium oxide base. The appearance includes micro-sphere, standard sphere, oval sphere, porous-sphere, ribbed sphere and so on. The main physical properties are as following:

Diameter: 1-8 mm;

Bulk density: 0.6－1.0 g/cm3；

Pore volume: 0.5－1.0 cm3/g；

Specific surface area: 150－350 m2/g.

Ring and cylinder catalyst carriers

We adopt the most advanced technique to produce ring and cylinder carriers with the raw materials of alumina, magnesia, various composite oxides and so on. The appearance includes raschig rings, single hole or porous cylinder, ribbed cylinders with single or multi holes, cylinders with flutes etc. Compared to the traditional technique, the new technique makes the products more uniform, which strengthens the following process (e.g.: carriers impregnated) and increase the service life of the catalysts.

The main physical properties are as following:

Diameter: 5-35 mm;

Bulk density: 0.4－1.3 g/cm3；

Pore volume: 0.1－0.5 cm3/g.

Cellular texture carriers

Mainly use alumina as the raw material and the appearance includes rectanglar, circular, oval and so on. The hole density is around 40-400 holes/inch2.
