AI Article Synopsis
- A one-step process using a brick reactor at low temperatures (300-500°C) effectively converted coconut shell biomass into a high-surface-area biochar-derived adsorbent with impressive characteristics (308 m²/g surface area, 2 nm pore diameter).
- Scanning electron microscope images confirmed the presence of well-developed nano-pores, indicating its classification as a nano-adsorbent, despite not requiring a separate activation process.
- This study uniquely demonstrates that coconut shell can be converted into a functional biochar-based nano-adsorbent at lower temperatures compared to previous methods involving other biomass sources, like oil palm empty fruit bunch.
Article Abstract
A one-step self-sustained carbonization of coconut shell biomass, carried out in a brick reactor at a relatively low temperature of 300-500°C, successfully produced a biochar-derived adsorbent with 308 m/g surface area, 2 nm pore diameter, and 0.15 cm/g total pore volume. The coconut shell biochar qualifies as a nano-adsorbent, supported by scanning electron microscope images, which showed well-developed nano-pores on the surface of the biochar structure, even though there was no separate activation process. This is the first report whereby coconut shell can be converted to biochar-derived nano-adsorbent at a low carbonization temperature, without the need of the activation process. This is superior to previous reports on biochar produced from oil palm empty fruit bunch.
