The biochar was produced by fast pyrolysis of potato peel waste (PPW) using the fluidized bed. The response surface methodology (RSM) and the central composite design (CCD) were employed for determining optimal adsorbents with the maximum H2S removal capacity. The operational parameters e.g. carbonization temperature (°C), duration (min) and space velocity (SV-Lmin−1kg−1) were chosen as independent...
Fluidized bed efficiently intensifies the carbonization step for biochar preparation by significantly reducing carbonization duration down to 6min at 450°C. The BET specific surface area of the char carbonized at 6min can reach 60m2/g. The produced porous biochar possesses both micropores and mesopores. The produced biochars are found to be alkaline. The degree of heterogeneity on the surface of biochar...
