This dataset is related to the treatment of poultry litters (PL) containing sawdust and chicken manure mixed in different varied proportions. Sawdust, chicken manure and PL were treated using hydrothermal carbonisation (HTC) and steam at high temperature. After HTC, physical activation for subsequent enhancement of hydrochar was furtherly treated with steam to produce activated carbon. The surface areas of the obtained activated carbons were measured by nitrogen adsorption and calculated using the Brunauer-Emmett-Teller (BET) formalism over a relative pressure range (0.05<P)⁄(P_0<0.30). The provided data are the nitrogen adsorption and desorption isotherms of the different activated carbons obtained. These data give an overall summary of the morphology of activated carbon produced from sawdust, chicken manure and poultry litters via HTC and steam.


Steps to reproduce

HTC experiments of poultry litters (PL) were performed in an unstirred 500 mL, high-pressure oven reactor using a slurry 1:10 w/w of PL to distilled water. To analyse the effect of the operating conditions on the feedstocks, the experiment were performed at different reaction temperatures of 200 and 220 ℃ at a residence time of 2 and 4 hours. The hydrochar obtained from the hydrothermal carbonisation was furtherly treated using physical activation in a nitrogen flow at 650 °C for 1 h. The nitrogen adsorption and desorption of the carbon material produced were measured using the TriStar II of Micromeritics and compared to carbon material produced from PL via steam at a higher temperature of 650-800 °C.
