Catalyst & Purification

• Our activated carbon is designed to minimize impurity leaching, contributing to stable catalyst support performance.

• We offer a product lineup ranging from powdered activated carbon to activated carbon filter depending on customers' equipment and requirements.

• Activated carbon is used to purify amine solutions employed to remove H₂S and CO₂ from natural gas and exhaust gas streams.

Catalyst plays a central role in chemical reactions, and even trace impurities or by-products can diminish their performance. Kuraray’s activated carbon lineup includes products used as catalyst supports and grades optimized through pore structure adjustment and removal of metal impurities.

In plating processes, impurities and by-products accumulate in plating baths over time, leading to reduced plating quality and shorter bath life. Kuraray’s activated carbon and activated carbon filter selectively adsorb organic decomposition products and metal impurities, helping maintain bath cleanliness.

Amine solutions (MEA, DEA, MDEA, and others) used in CO₂ recovery and gas purification processes accumulate thermal decomposition products, reaction by-products with acidic gases, and organic impurities during operation. These impurities can cause solution degradation, corrosion, and reduced absorption efficiency. Kuraray’s activated carbon selectively adsorbs and removes these impurities, extending solution life and protecting equipment.
