Arhar is one of the most cultivated crops in Asian countries; arhar dal is the main yield from the arhar crop. After crop harvest, arhar stalks are mostly used as firewood which causes pollution and has a bad impact on the environment. The present research work is to convert these arhar stalk fibers into biochar. Arhar fiber powder is subjected to pyrolysis process to prepare biochar. Different parameters involve in the pyrolysis process, in the current study effect of temperature on biochar yield was investigated. SEM and TGA analyses are performed on arhar biochar to know the thermal stability of biochar. From the experiment results, it was found that temperature has a great impact on surface structure and thermal stability of biochar. The surface morphology of biochar materials was studied by SEM analysis, it was found that with the increment in pyrolysis temperature there was enhancement in porosity of biochar materials. From the TGA analysis, it was observed that biochar materials prepared at high temperature exhibited high thermal stability.
