Microwave-Assisted hydrothermal carbonization and characterization of Amazonian biomass as an activated carbon for methane adsorption

Fuel, Год журнала: 2023, Номер 358, С. 130329 - 130329

Опубликована: Ноя. 8, 2023

Activated carbons were prepared from Amazonian biomass by means of microwave-assisted hydrothermal carbonization and activated with CO2. These materials investigated as methane adsorption sorbents. The samples submitted to textural investigations comprehensive characterizations using scanning electron microscopy, Transmission energy dispersive X-ray diffraction, Raman FTIR spectroscopy. Values specific surface areas pore volume ranged 0.35 cm3/g 0.50 840 1096 m2/g respectively, this value is likely attributed the high selectivity CO2/CH4 combining large area, narrow micropores. results stability tests attested robustness carbon an adsorbent under specified operating conditions assessment, which included measurements after first cycle well fifth, tenth, fifteenth cycles, revealed a remarkable consistency in its behavior, maximum recorded standard deviation 0.05. Isosteric heat showed decline Qst 21 20 coverage increases 0.1 0.5, indicating energetic transformation occurring during process. AC C shows highest capture capacity 150 V/V at 40 bar pressures CH4/CO2 0.49 up 1 bar.
