| Popis: | This study focuses on isotherms adsorption of natural gas components i.e. methane, ethane, and propane on five commercial activated carbons to determine their different behaviors towards each compound. These five commercial activated carbons have different textures that are supposed to affect their adsorption capacity. The experiments were carried out at 303 K within a pressure range of 0–3 MPa using a homemade manometric adsorption device. A comprehensive process was also detailed with a step-by-step calculation. The obtained data were then fitted into the modified Langmuir model in order to justify the mono-layer coverage. Hence, the relationship between the Langmuir adsorption capacities and different textural properties were plotted, and only the specific area showed its direct influence. The outcome also turned out that the most promising activated carbon is the one that possesses not only the highest specific surface area but also has an adequate balance between the microporous and mesoporous volumes. |
