Abstract: The present disclosure provides a method for predicting a lattice defect in a metal-organic framework (MOF) membrane. The method comprises acquiring a number n of a ligand during preparation of the MOF membrane, and acquiring a theoretical number m of connections formed between a core secondary building unit and a surrounding secondary building unit; setting a number of collisions of the ligand with the core secondary building unit and the surrounding secondary building unit; and calculating an expected value of a number of connections formed on lattices based on a collision probability, wherein the number of collisions is 1 or 2.

Abstract: The present disclosure relates to a mixed matrix carbon molecular sieve (CMS) membrane, a preparation method of the mixed matrix CMS membrane, and use of the mixed matrix CMS membrane in C2H4/C2H6 separation, and belongs to the technical field of membrane separation. The present disclosure solves the problem that the CMS materials in the prior art exhibit low selectivity and low flux during an ethylene/ethane separation process. In this patent, C3N4 is used as a filling particle to prepare a mixed matrix membrane (MMM), and the MMM is pyrolyzed to prepare a CMS membrane. The C3N4/6FDA-DAM MMM has prominent C2 separation performance.
