Silicon Carbide is the primary component of this catalyst carrier, besides a few kaolin and auxiliaries.
Features of catalyst: Excellent performance on mechanical thermal, electrical and chemical properties which including good resistance of corrosion, high abrasion resistance , good thermal conduction, low thermal expansion coefficient and high crush strength under high temperature.
Advantage
1) low pressure drop
2) large surface area, can carry large amount of activity with the same thickness of coating.
3) maintain service life of catalyst and increase capacity of catalyst.
4) make catalyst has high selectivity.
