Pore Space Partition on Sulfonate-rich Metal-Organic Framework for Purification of Methane from Natural Gas

Abstract

By implementing the pore space partition (PSP) strategy on a sulfonate-rich acs-type metal-organic framework (MOF), we developed a new pacs structure, which features segmented pores with abundant O/N interacting sites. This structure selective uptake C2H6 and C3H8 from ternary mixture of C2H6/C3H8/CH4 with high selectivity and capacity, enabling effective purification of CH4 from natural gas through one adsorption process.
