Carbon sorbents based on oxidized Kuznetsk Basin coal

Аннотация

Some physicochemical properties of carbon adsorbents produced by chemical activation with alkali are determined: specifically, their total ash content, the content of water-soluble ash, the total iron content (recalculated for Fe³⁺), and the content of water-soluble iron compounds. Their content of water-soluble ash and the total iron content are minimal; no water-soluble iron compounds are observed in the sorbents. However, the total ash content in the sorbents is impermissibly high. With increase in potassium content in the initial content, the total ash content of the sorbents is reduced to 16.5%.
