Two-dimensional imine covalent organic frameworks for methane and ethane separation: A GCMC simulation study

Separation of methane and ethane using porous materials is a challenge. Size exclusion will reduce the working capacity and increase the difficulty of material fabrication. Covalent organic frameworks (COFs) are hopeful due to the adsorption selectivity of C2H6/CH4 and other advantages. In this paper, we used the grand canonical Monte Carlo (GCMC) simulations to study the adsorption behavior of 1171 theoretical two-dimensional (2D) imine COFs,...
