I. Product introduction
AS-731 adsorbent is a kind of special spherical aluminum oxide, whose characteristics and advantages include:
* The optimized distribution of bore diameters makes adsorption capacity higher.
* The regular structure of bore passages increases adsorption velocity and reduces the height of mass transfer zone
* The materials with large specific surface area can extend the service life of adsorbent bed.
II. Technical introduction
AS-731 hybrid adsorbent can be used to remove the impurities of hydrocarbon materials, which has high-capacity adsorption for polar molecules like water, Oxidants, organic sulfur and nitrogen compounds. It has high selection and adsorption capacity for light acid gas like CO2, H2S and COS. It removes all these and other impurities to ultra-low emission levels to ensure the activity and function of the catalysts for polymerization. AS-731 adsorbent has a wide range of olefin purification functions. This adsorbent alone can replace the previously required multiple adsorbent mixers.AS-731adsorbent can be reused at high temperature through purging or exhaust.
