Abstract

• Biochar is a solid material that is produced by heat decomposition of biological wastes biomass. The experiments were carried out to study the characterization of the Coconut Husk and Areca nut Husk biochar. The Coconut Husk and Areca nut Husk were heated at 300˚C for 1h in muffle furnace and ground into the uniform powder. The most important properties that provide information about the fuel were proximate analysis such as moisture, ash content, volatile matter and fixed carbon contents. The fixed carbon content of Coconut Husk and Areca nut Husk were measured to be 10 mf wt%. The structural characterizations of Coconut Husk and Areca nut Husk biochar were identified by X-ray diffraction (XRD) technique. The Fourier transform infrared spectroscopy (FTIR) analysis showed the presence of a variety of functional groups of Coconut Husk and Areca nut Husk biochar. Scanning Electron Microscope images of the biochar were obtained for morphological features analysis.
