Preparation and Characterization of Biochar From Groundnut Shells

The aim of this work was to produce renewable biochar from groundnut shells as a potential method of treating wastewater. In this work, the biomass of peanut shells was pyrolyzed at 500, 600, and 700 oC to create biochars (BC-500, BC-600, and BC-700). Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy, and energy dispersive X-ray spectrometry (SEM and EDX) were used to characterize the biomass sample and the biochars they formed in order to assess their potential. According to previous research, biochar has superior porous properties over raw biomass, as this is created during the pyrolysis process, which occurs when water loss increases during dehydration. Additionally, we discovered that raising the pyrolysis temperature significantly enhanced the biochars' morphology and porosity.
