Abstract

The yield and properties of active carbons (AC) produced by combined pyrolysis and activation of the mixtures: hydrolytic lignin – oil slime, brown coal – oil slime and hydrolytic lignin – brown coal – oil slime have been compared. The yield of AC from a triple mixture is lower than that from brown coal – oil slime, but higher than that of lignin – oil slime mixtures. The reached yield (15-20 %) and surface area (about 400 m2/g) of AC from triple mixture hydrolytic lignin – oil slime –brown coal are enough for their industrial using.
