Activated alumina for dechlorination, also known as chlorides removal alumina, is a specially engineered aluminum oxide adsorbent designed for the efficient removal of chlorine-containing impurities from gas and liquid streams. It exhibits excellent adsorption performance toward free chlorine, hydrogen chloride, and a variety of inorganic and organic chloride compounds.
In addition to its strong adsorption capability, chlorides removal alumina can promote the catalytic decomposition or conversion of certain organic chlorides, such as methylene dichloride and other chlorinated hydrocarbons, helping to reduce chloride contamination and protect downstream catalysts, process equipment, and product quality.
The uniform pore distribution of chlorides removal alumina, allows rapid mass transfer and efficient utilization of active adsorption sites, resulting in high chloride removal efficiency and extended operating cycles. Moreover, chlorides removal alumina can maintain stable performance over a wide range of temperatures and pressures.
In petroleum refining and petrochemical processing, activated alumina is widely used for the removal of hydrogen chloride generated during hydroprocessing, catalytic reforming, chlorinated feedstock treatment, and various hydrocarbon purification processes. Therefore, chlorides removal alumina is extensively applied in the purification of natural gas, liquefied petroleum gas (LPG), synthesis gas, hydrogen streams, and various chemical intermediates.
