Chemshun
Chemshun activated alumina has a large capacity of absorption, large surface area, high strength and thermal stability, which is widely used as an absorber, desiccant and catalyst carrier in chemical, petrochemical and fertilizer industry. It can also widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the water gas.
Main Features
-- Our Activated Alumina Balls are low dusting, high capacity desiccant especially for use Hi package dryers.
-- Activated Alumina Balls have high moisture adsorption capacity
-- Less energy is required for regeneration. The regeneration temperature is between 140 C to 21OC
-- It works well in heat less air dryers because of its ease of desorption, high resistance to attrition and high crushing strength
-- Activated Alumina has excellent thermal stability
