Construction of saturated coordination titanium-based metal–organic framework for one-step C2H2/C2H6/C2H4 separation

• Construction saturated coordination Ti-MOF for alkanes-selective adsorption. • C 2 H 6 and C 2 H 2 can be selective adsorbed simultaneously on the adsorbents. • One-step separate C 2 H 4 from ternary C 2 H 6 /C 2 H 2 /C 2 H 4 mixture. • The synthesized Ti-MOFs show good structural stability for C 2 H 4 purification. The slight differences between ternary components of C 2 hydrocarbons make the separation of C 2 H 2 /C 2 H 6 /C 2 H 4 mixtures...
