Abstract
This paper explains about the production of biochar from areca catechu tree dust and its various properties. The biochar was produced through pyrolysis using a fixed bed rector with the particle size of the biomass feedstock in the range of 0.5-1.0 mm. The temperature used for pyrolysis was about 450 °C along with a heating rate of 10 °C/min. The heating value of the biochar was 22.93 MJ/kg, while for raw biomass it was only 13.2 MJ/kg. The biochar was alkaline in nature with high pH value. The FTIR (Fourier Transform Infrared) analysis identified the functional groups of some aromatic hydrocarbons along with few carbonyl and alkene groups. The morphology of the biochar indicated a microporous surface with the average pore size diameter of about 1.87 µm. The overall structure of the biochar was amorphous in nature with partial crystalline cellulose.
