Grain coal


Combines a premium quality activated carbon with a proprietaty blend of catalytic inorganic phase and metal oxides, which results in an extraordinary hydrogen sulfide (H2S) absorption capacity in oxygen-poor streams. Unlike other medias, H2S is not converted to sulfuric acid (H2SO4), but to elemental sulfur (S), which is accumulated in the carbon micropores. BOIN Carb ODR is also a good absorbent for other acidic gases, such as sulfur dioxide(SO2), methylmercaptan and volatile sulfur compounds (VSCs).
