Carrier for Catalysts
Product Name:
Carrier for Catalysts
Model:
12
Description:
Honeycomb monoliths with their high achievable surface areas per unit volume are utilized in catalyst carriers, active catalysis and air flow distributors, also used for heat exchanger processes, electro-chemical applications and carrier bodies for biological applications and still utilized in catalytic converters for purifying vehicle exhaust gas, reducing carbon monoxide, smog ect.. In addition to the listed standard geometries and materials of construction honeycomb monoliths are also available in other ceramic materials of construction and geometrical configurations.
Cordierite Honeycomb Monolith
Product Name:
Cordierite Honeycomb Monolith
Model:
12
Description:
Cordierite is a magnesium alumina silicate material, which has very low linear expansion, low coefficient of thermal expansion and excellent resistance to thermal shock. Cordierite also offers an excellent range of mechanical strength, porosity criteria, and excels in cost-effective extruded and dry-pressed forms. Cordierite Honeycomb Monoliths are divided into two types: porous type and dense type.

Raschig Ring
Product Name:
Raschig Ring
Model:
12
Description:
Raschig ring is a form of random packing and is used in commercial fractional distillation columns to reduce pressure loss (versus using trays), while maintaining good efficiency and economy. Dohntec Raschig Ring Packing is proven in a wide range of mass transfer applications.
Pall Ring
Product Name:
Pall Ring
Model:
12
Description:
The Pall ring is a kind of new type and high efficient packing that is improved on the basis of the Rasching ring. Dohntec pall ring is a proven design that provides higher capacity and lower pressure drop than trays and other random packings. The opened cylinder walls and inward bent protrusions of the Pall Ring allow greater capacity and lower pressure drop than standard cylindrical rings.
Ceramic Saddle
Product Name:
Ceramic Saddle
Model:
12
Description:
Ceramic saddle is improved from the arc saddle, it changes the both arched surface to rectangular surface and makes the interior and exterior radius of curvature different, this construction overcomes the problem of nesting basically, it makes porosity distributed even and improves the distribution of the fluid , greater capacity and lower pressure drop than Raschig ring.
Ceramic Super Saddle
Product Name:
Ceramic Super Saddle
Model:
12
Description:
Ceramic Super Saddle is the improvised version of the original saddle. It's designed to give enhanced internal gas and liquid distribution. The unique scalloped edge is the key to the product's high performance in terms of greater capacity, low pressure drop and high rates of mass transfer. It overcomes the problem of nesting that is found in ordinary saddles.
Cascade Ring
Product Name:
Cascade Ring
Model:
12
Description:
Cascade ring, a packing media designed to give enhanced capacity, increased efficiency and mechanical strength over the older style Pall ring packing. The height/diameter ratio of the packing is 0.5 which is only half that of the known Pall Ring.
Ceramic Cross-Partition Ring
Product Name:
Ceramic Cross-Partition Ring
Model:
12
Description:
Ceramic Cross-Partition Ring is a packing designed basically from the Raschig Ring with the cross-partitions inside to increase the surface and enhance the transfer efficiency. It is usually used extensively for the supporting packing at the bottom of tower.
