“…As for the mixture of C 3 and C 2 with equal proportion, the IAST selectivities are 15.3, 88, and 5.9, for C 3 H 8 /C 2 H 2 , C 3 H 8 /C 2 H 4 , and C 3 H 8 /C 2 H 6 , and 19.2, 121.8, and 5.9 for C 3 H 6 /C 2 H 2 , C 3 H 6 /C 2 H 4 , and C 3 H 6 /C 2 H 6 , respectively (Figure f), which are significantly higher than FJI-C1 (4.1, 9.0, and 6.8 for C 3 H 8 to C 2 H 2 , C 2 H 4 , and C 2 H 6 ), and UPC-35 (4.9. 6.9, and 5.5 for C 3 H 6 to C 2 H 2 , C 2 H 4 , and C 2 H 6 ; 4.9, 7.0, and 5.6 for C 3 H 8 to C 2 H 2 , C 2 H 4 , and C 2 H 6 ) . Interestingly, UPC-98 shows a relatively high adsorption selectivity toward C 2 H 2 /C 2 H 4 (3.1) compared to C 2 H 2 /C 2 H 6 (0.9) at room temperature.…”
