Xingsen Acid-Washed Activated Carbon is produced from selected carbonaceous raw materials and treated through a controlled acid-washing process to reduce ash and mineral impurities.
The acid-washing process is particularly valuable when cleaner adsorption media and tighter control of inorganic impurities are required. By removing part of the mineral matter associated with activated carbon, the treatment can reduce ash content and, depending on the raw material and process conditions, help expose or unblock part of the pore structure.
Our acid-washed activated carbon is available mainly in coconut shell-based grades, with coal-based grades also available for selected applications. Granular and powdered forms can be supplied in different particle sizes and adsorption specifications.
Unlike standard activated carbon, which is often selected primarily for adsorption capacity, acid-washed grades are chosen when adsorption performance and product purity need to be considered together.
Xingsen Acid-Washed Coconut Shell Activated Carbon is produced from selected coconut shell carbon and treated through a controlled acid-washing process to reduce ash and mineral impurities.
Its combination of high adsorption capacity, low ash content, and controlled inorganic impurities makes it particularly suitable for applications where the purity of the adsorption media is as important as its adsorption performance.

Custom particle sizes and specifications are available according to application requirements.
In addition to coconut shell grades, Xingsen supplies acid-washed coal-based activated carbon for selected industrial and water treatment applications.
Acid washing helps reduce mineral impurities and ash content in coal-based activated carbon. These grades can be considered when the process requires controlled ash levels, specific pore characteristics, mechanical properties, or a different cost-performance balance.
