A Review on the thermochemical conversion of sugarcane bagasse into biochar

Cleaner Materials, Journal Year: 2022, Volume and Issue: 6, P. 100162 - 100162

Published: Oct. 31, 2022

Sugarcane bagasse (SCB) is the fibrous lignocellulosic residue left over after crushing sugarcane to extract juice for sugar and ethanol production. In this review, a concise overview of existing thermochemical technologies production biochar from SCB its potential applications presented discussed. Some used so far in regard include pyrolysis, gasification, hydrothermal carbonization, torrefaction. However, pyrolysis was found be most widely among them. These processes can affected by several operating conditions such as temperature, heating rate, particle size, residence duration, with temperature being significant efficient variable influencing quality biochar. The yield reported literature ranged 14 % 56 %. A higher obtained at lower than one because decomposes temperatures (>500 °C). has promising agriculture environment, including soil amendment, adsorbent water wastewater treatment, supplementary cementitious material, amongst others. knowledge gaps were also stated study, cost analysis comparison utilizing fuel industries become highly carbon material wide range variety sectors.
