Crushed activated charcoal STKA(K)

Crushed activated charcoal STK-A (K) is produced from brown coal from the Bolshesyrsky deposit of the Kansk-Achinsky coal basin. The production process is crushing, gasification at high temperature in stationary batch furnaces. STK-A (K) coal is a high-strength effective sorbent for a wide range of applications. The particle size is 2.5-8 mm. It is made according to TU 20.14.71-001-49584260-2020
