Abstract Liquid‐phase exfoliation, a technique for enhancing the properties of biochar, has been recognized as effective, circumventing limitations other methods such high expenses, scalability, and complexity. This study explored synergistic effect achieved by combining chicken feathers with elephant grass to create composite feedstock biochar production. The was subjected liquid‐phase exfoliation using acid acetone. Elemental analysis indicated that co‐carbonization combined biomass produced an enriched hybrid biochar. oxygen content in both routes (acid acetone) increased, increase decrease carbon acetone respectively. Textural revealed significant enhancement, surface areas acid‐exfoliated more than twice size pore volume exfoliated samples double Microscopic examination rougher, porous structures biochars comparison smooth, cohesive Functional group showed presence aromatic rings, carbocyclic group, alkene, suggesting potential applications adsorption. provides efficient method enhance properties, benefiting industries reliant on production utilization improving product quality, sustainability, environmental impact.

Comparative assessment of biochar produced from LDPE and neem leaves using batch and semi-batch biomass fuel-based reactors

Biofuels, Journal Year: 2023, Volume and Issue: 15(6), P. 677 - 687

Published: Nov. 10, 2023

This research aims to investigate and compare the properties of biochar derived from low-density polyethylene (LDPE) neem leaves, utilizing both batch semi-batch biomass fuel-based reactors for co-carbonization. While previous studies have primarily employed electrical-powered or reactors, this study introduces innovative approach a reactor, marking significant advancement in production. The co-carbonization process lasted ∼2 h batch-based system nearly 3 system. achieved higher temperature peaks comparison In terms yield, generated yield 30.35%, while yielded 17.3%. Through BET analysis, it was determined that produced using reactor had surface area 227 m2/g pore diameter 2.116 nm. Similarities differences functional groups among samples were identified through FTIR analysis. By EDX spectroscopy, observed contained seven elements, whereas semi-batch-reacted sample similar elements but lacked nitrogen, potassium, magnesium. exhibited an increased carbon content, concentrations other decreased when compared batch-reacted sample. can be applied various applications, including water treatment, energy conversion, storage. findings contribute sustainable waste management practices, sequestration efforts, development solutions industries.
