Adsorption of Lower Alkanes CH4, C2H6, C3H8, and n-C4N10 and Their Mixtures on Highly Active Microporous Carbon Adsorbent
摘要
Abstract
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.
