Abstract

The biochar was produced from fast pyrolysis of reed black liquor using fluidized bed. Response surface methodology and the central composite design (CCD) were employed for determining optimal adsorbents with maximum H2S removal capacity. The operational parameters such as carbonization temperature (°C), duration (min) and space velocity (SV, L min−1 kg−1) were chosen as independent variables in CCD. The statistical analysis indicates that the effects of carbonization temperature, duration, SV and combined effect of carbonization temperature and duration are all significant to the H2S removal capacity. The optimal condition for achieving the maximum H2S adsorption capacity for biochar is obtained as the follows: carbonization temperature (500°C), duration (5.7 min), SV (7300 L min−1 kg−1) with H2S removal reaching 60 mg g−1. The dynamic experimental results indicate a good performance in H2S removal by the produced biochar.
