摘      要：The separation of propylene and propane is an important but challenging process,primarily achieved through energy-intensive distillation technology in the petrochemical ***,we reported two natural C4linkers based metal–organic frameworks(MIP-202 and MIP-203)for C_(3)H_(6)/C_(3)H_(8)*** isotherms and selectivity calculations were performed to study the adsorption performance for C_(3)H_(6)/C_(3)H_(8)*** show that C_(3)H_(6)/C_(3)H_(8)uptake ratios(298 K,100 kPa)for MIP-202 and MIP-203 are 2.34 and 7.4,respectively.C_(3)H_(6)/C_(3)H_(8)uptake ratio(303 K,100 k Pa)for MIP-203 is up *** mechanism for enhanced separation performance of C_(3)H_(6)/C_(3)H_(8)on MIP-203 at higher temperature(303 K)was revealed by the in situ PXRD *** adsorption selectivities of C_(3)H_(6)/C_(3)H_(8)on MIP-202 and MIP-203(298 K,100 k Pa)are 8.8 and 551.4,*** mechanism for the preferential adsorption of C_(3)H_(6)over C_(3)H_(8)in MIP-202 and MIP-203 was revealed by the Monte Carlo *** cost of organic ligands for MIP-202 and MIP-203 was lower than that of organic ligands for those top-performance *** work sets a new benchmark for C_(3)H_(6)sorbents with high adsorption selectivities.
