Low-cost palm shell was used as a precursor for preparation of porous carbons via chemical impregnation with K2CO3 and microwave heating. Volumetric adsorption setup was used to measure the adsorption capacity of methane at 303.15 K under pressure up to 4 bars. The methane adsorption data was modelled by Langmuir, Freundlich, and Dubinin–Radushkevich (DR) isotherm equations. Langmuir and Freundlich models were found to have the best fit than DR isotherm. The kinetics of methane adsorption on the microwave porous carbon followed pseudosecond-order model equation. The highest methane adsorption capacity obtained was 3.533 mmol/g at 4 bar and 303.15 K. It was noticed that there is increase in adsorption with increased in initial pressure. The porous carbon displayed good adsorption characteristics for methane. |
