Activated alumina Activated alumina for desiccant Activated alumina ball
This kind of product is X-ρ form active aluminum oxide dryer.Its appearance is white spheric particle with strong adsorptive capacity of moisture,its drying depth(dew point)can be below-70°C under certain operating and regenerating conditions.It is a high efficiency dryer for drying micro amount water.This product is widely used as dryer in gas phase,liquid phase and auto-instrument wind drying of petrochemical,textile and oxygen-making industries,PSA in air-seperation etc..Due to high heat-adsorption quantity of single molecular adsorbing layer,so,it is very suitable for the use of heat-free regeneration device.
Main technical Indexes:
Applications: It is mainly used in gaseous and liquid desiccation in petrochemical industry. In is also widely applied as a dryer in textile industry, oxygen making industry and automatic instrument equipments with non-heat regeneration.
