Additional Information
1. Product Description
High surface area, large heat capacity, low thermal expansion, resistant to corrosion and high temperature, ceramic honeycomb monoliths have been well used in chemical, metallurgical, gas and environmental protection industries. The main usage is as follows:
Tower packings--With high surface area, even distribution of fluid and, efficient in mixture separation in chemical & petrochemical industries.
Catalyst carriers--Reduce the oxidation temperature of VOC in purification of industrial exhaust gases in RCO systems and automobiles.
Regenerative heat step-up transformer--Large heat capacity, low resistance to fluid and energy saving up to 40-70% in RTO systems.
Gas combustion distributor--Distribute the heat uniformly, and make the combustion completely. It can save energy more than 10%.
Kiln furniture in refractory industries--Low bulk density and high thermal efficiency.
