Extraction and Characterization of Carbon from Bio Waste

This study is an effort to utilize agricultural biomass rice husk for useful applications. The biomass has been milled and then pyrolysed at three different temperatures (800, 900 and 1000 °C). TGA analyses performed on the samples prove the presence of lignocellulosic materials that suggests dissociation of higher molecular weight compounds to low molecular weights, on slow heating under inert conditions. Further, the XRD analyses suggest the presence of amorphous silica and carbon in all the samples. However, the morphological results of biochars have shown tar formation.
