Study of Pore Length and Chemical Composition of Charcoal that Results from the Pyrolysis of Coconut Shell in Bolaang Mongondow, Sulawesi, Indonesia

Abstract

Charcoal of coconut shell is produced by pyrolysis at 300 °C and chemically activated using HCl. Both pyrolysis charcoal and chemical activation were measured and analyzed by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), and Energy Dispersive Spectroscopy (EDS). The functional groups found OeH, aliphatic CeH, aromatic C]C, CeO, and aromatic CeH. The distribution of pyrolysis charcoal pore length and chemical activation increased from 362 nm-1.02 μm to 1.10 μm-1.52 μm. The composition of carbon elements in the mass % of pyrolysis charcoal and chemical activation increased from 86.11% to 88.93%.
