CO-type gas masks use catalytic cartridges. The filter box is filled with a suitable catalyst.The traditional catalyst is hopcalite catalyst, which has been used for nearly one hundred years. It is based on activated carbon as a carrier, and uses a mixture of copper, manganese and other oxides as an active component.

A large amount of ozone is produced in the process of corona treater. It is necessary to remove ozone caused by corona treater.

The catalytic destruction of ozone is the most used process, because it is easy to install on new and existing ozone generating systems and it is cost effective.

    Earthy graphite is also called amorphous graphite, aphanitic graphite or microcrystalline graphite. Earthy graphite ore is gray-black, steel-gray, generally dull in luster, and has dense massive, earthy, layered, and sheet-like structures.

There are many kinds of recarburizer, calcined anthracite(also called CAC), calcined petroleum coke(CPC), graphitized petroleum coke(GPC).  Electrode scraps and graphite crucibl

he carbon molecular sieve (CMS) is a slit-like micro-pore structure of carbon-based adsorbents, capable of separating molecules with different molecular sizes
