Properties of Active Carbons Produced by Thermochemical Transformation of Lignin, Brown Coal and Oil Slime Mixtures

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.
