Activated carbons prepared from hazelnut shells, walnut shells and peanut shells for high CO2 adsorption

Activated carbons prepared from hazelnut shells, walnut shells and peanut shells for high CO2 adsorption

Research treats about producing activated carbons for CO2 capture from hazelnut shells (HN), walnut shells (WN) and peanut shells (PN). Saturated solution of KOH was used as an activating agent in ratio 1:1. Samples were carbonized in the furnace in the range of temperatures 600°C–900°C. Properties...

Saturated solution of KOH was used as an activating agent in ratio 1:1. Samples were carbonized in the furnace in the range of temperatures 600°C–900°C. Properties of carbons were tested by N2 adsorption method, using BET equation, DFT method and volumetric CO2 adsorption method. With the increase of carbonization temperature specific surface area of studied samples increased. The largest surface area was calculated for samples carbonized at 900°C and the highest values of CO2 adsorption had samples: PN900 at 0°C (5.5 mmol/g) and WN900 at 25°C (4.34 mmol/g). All of the samples had a well-developed microporous structure.https://doi.org/10.1515/pjct-2017-0025activated carbonbiomassnutshellsco2 adsorption
