Abstract:

Natural gas is a highly efficient energy source subject to growing demand. Natural gas contains H2S, which can harmhuman health and cause equipment corrosion and environmental pollution. Effective H2S adsorbents are necessary to overcome these problems. Grand canonical Monte Carlo (GCMS) simulations were performed to study the selectivity and working capacity (pressure swing adsorption (PSA) and vacuumpressure swing adsorption (VSA) processes) of H2S in 33 kinds of stable metal-organic frameworks (MOFs), with the aim of separating H2S from H2S/CH4 gas mixture. ZIF-80, Zn2-bpydtc, CAU-1-(OH)2, and CH3O-MOFa were suitable materials for the VSAprocess. CAU-1-(OH)2 and CH3O-MOFa were suitable for the PSA process. The structures of materials exhibiting high selectivity and working capacity suggested that appropriate functionality and small pore sizes were important for high selectivity. MOFs with ―Cl, ―OH
