Abstract :In this study, the performance of tobacco biochar-AlCl 3 composite for CO 2 capture was investigated. Biochar-AlCl 3 composites were prepared at different blend ratios insert ignore into journalissuearticles values(10:0.4; 10:2; 10:4, wt./wt.); and used for CO 2 capture experiments to determine the optimal Al metal content at which CO 2 adsorption was highest. Biochar composites were produced through slow pyrolysis under inert nitrogen atmosphere in a fixed bed reactor at 600 o C for 3h. Properties of biochar-metal composites and raw biochar samples were characterized with SEM-EDS, XRD and FTIR analysis. CO 2 experiments were conducted in TGA under N 2 atmosphere with a flow rate of 50 ml/min at 25°C. The maximum CO2 adsorption was observed as 59.97 mg/g for biochar: AlCl 3 composite at a ratio of 10:2. Finally, results of study showed that biochar-AlCl 3 composites have great potential as a CO 2 capture material due to its low-cost, sustainability and CO 2 capture capacity.
