Abstract

• Biochar derived from biomass waste is accepted as multifunctional material for various applications according to its specific characteristics. It is therefore popular to investigate biochar properties under the improvement of research application. In this study, biochar derived from Dracontomelondao fruit shell (DD nut) (English: Pacific Walnut) from Moe Nyin Township, Kachin State was prepared by different pyrolysis temperatures (400, 500 and 600ºC) at one hour each. Structural properties of the resulted biochar were characterized by X-ray Diffraction (XRD) technique, infrared spectroscopy (FTIR), and Scanning Electron Microscopy (SEM) technique. Changes in properties of Dracontomelondao biochar with different temperatures were investigated.
