Adsorption of Lower Alkanes CH4, C2H6, C3H8, and n-C4N10 and Their Mixtures on Highly Active Microporous Carbon Adsorbent
A comparative study of the adsorption behavior of methane, ethane, propane and n-butane on the supermicroporous adsorbent ACW with a high micropore volume (1.44 cm3/g) and a wide distribution of pore sizes. The gas adsorption isotherms were measured by the volume–weight method at temperatures of 303, 313, 323, and 333 K in the pressure ranges of methane (0.1–40 MPa), ethane (0.01–3.8 MPa), propane (0.01–0.9 MPa), and n-butane (0.01–0.19 MPa). The IAST method was used to calculate the adsorption of binary mixtures CH4/C2H6, CH4/C3H8, and CH4/H10 with component contents of 98/2, 95/5, 92/8, and 90/10 mol %, respectively. The potential selectivity of the ACW adsorbent in adsorption gas separation processes was assessed for their further use.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
