The removal of C H and C H from C H streams is of great significance for feedstock purification to produce polyethylene and other commodity chemicals but the simultaneous adsorption of C H and C H over C H from a ternary mixture has never been realized. Herein, a robust metal-organic framework, TJT-100, was designed and synthesized, which demonstrates remarkably selective adsorption of C H and C H over C H . Breakthrough experiments show that TJT-100 can be used as an adsorbent for high-performance purification of C H from a ternary mixture of C H /C H /C H (0.
