Abstract

• Biomass is organic material that comes from plants and animals, and it is a renewable source of energy. The coconut and peanut shells biochar were produced by heat decomposition of these biomasses. These biomasses were heated in a muffle furnace at 300 °C, 400 °C and 500 °C for 2 h respectively. The aim of this study was to use coconut and peanut shells in the preparation of activated carbon. The elemental compositions of these samples were analyzed by X-ray fluorescence (XRF). The surface morphology of these biomasses was determined by Scanning Electron Microscopy (SEM). Phase formation and structural properties of samples were characterized by X-ray Diffraction (XRD). Fourier Transform Infrared Spectroscopy (FTIR) was used to determine the chemical properties of the coconut and peanut shells biomass. In this research, the physicochemical characteristics of coconut and peanut shells biomass with activated carbons (ACs) were reported and discussed rapid deployment of renewable energy and energy efficiency and technological diversification of energy sources would result in significant energy security and economic benefits.
