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.

Co-transport and deposition of fluoride using rice husk-derived biochar in saturated porous media: Effect of solution chemistry and surface properties

Environmental Technology & Innovation, Journal Year: 2023, Volume and Issue: 30, P. 103056 - 103056

Published: Feb. 10, 2023

Fluoride (F−) contamination in water is a global health concern, threatening the well-being of millions. This study investigated role ZnCl2/FeCl 3-rice husk-modified biochar (Zn-BC and Zn/Fe-BC) treating F−-contaminated surface groundwater under influence varying solution chemistry, co-existing ions, biochar-amended through column transport experiments. Modified showed maximum F− adsorption, 99.01% 91.90% using Zn/Fe-BC Zn-BC, respectively, than 85.87% raw (R-BC). Raw/modified biochars were characterized with FESEM-EDAX, FTIR, XRD, particle size, area, electro-kinetic potential, point zero charge analyses. Langmuir pseudo-second-order kinetic could explain that F−-biochar interactions are dominated by chemisorption at ambient temperature while physisorption higher temperatures. The salt concentrations co-occurring ions reduced sorption Zn/Fe-BC. Increased strengths led to electrophoretic mobility particles, i.e., biochar-biochar particles attract each other increase hydrodynamic diameter, which ultimately reduces active sites on for fluoride adsorption. Co-transport deposition saturated porous media revealed lower biochar, adsorption was observed 10 mM strength. Biochar governed electrostatic interactions, whereas mainly occurs chemisorption. In rural areas, hand pumps generally applied drinking cooking; thus, biochar-mediated sand columns can be utilized defluoridation. Thus, as potential bio-adsorbent natural optimum preparation treatment costs.
