Thermal analysis of activated carbons from biomass

Thermal analysis was applied in investigation of activated carbons (ACs) from different biomass: beech and hornbean wood, pine cones, walnut shell, miscanthus giganteus, corn stalks and switchgrass. The precursors were pyrolysed at the temperature of 600°C. Carbonizates were activated with potassium hydroxide at the temperature of 750°C for 15 minutes. On the basis of thermogravimetric analysis (TGA) it was found that activated carbons obtained from different types of biomass show different resistance to thermal degradation process. The thermostability of activated carbons from biomass of annual plants is smaller compared to the thermal resistance of carbons adsorbents from wood.
