Coal honeycomb activated carbonIt is a traditional and modern artificial material, also known as carbon molecular sieve, with a chemical formula of C. CAS: 64365-11-3 EINECS: 264-864-4. Since its inception a hundred years ago,activated charcoalThe application fields are expanding day by day, and the number of applications is constantly increasing.

main purpose

Decolorization and filtration to decolorize colored liquids. Absorb various gases and vapors. Used for chromatographic analysis. Measure reducing agents for methanol, tin, and silicon. Granular materials can be used as carriers for catalysts.

Classification of types

Due to differences in raw material sources, manufacturing methods, appearance shapes, and application scenarios, there are many types of activated carbon, and so far there is no precise statistical material available, with approximately thousands of varieties.
