Abstract

The invention relates to the technical field of membrane separation, and in particular, relates to a preparation method of a reinforced Pebax mixed matrix membrane. According to the preparation method of the reinforced Pebax mixed matrix membrane, a metal-organic framework (MOF) material is doped into a Pebax-1657 matrix to prepare the mixed matrix membrane, the restrictive effect between permeability and selectivity of the Pebax membrane is improved, and the CO2 permeability coefficient and CO2/N2 selectivity are greatly improved.

Description

technical field [0001] The invention relates to the technical field of membrane separation, in particular to a method for preparing a strengthened Pebax mixed matrix membrane. Background technique [0002] In recent years, global CO 2 Emissions have exploded, causing a great impact on the ecological environment. Compared with conventional high energy consumption CO 2 Capture technologies, such as amine absorption and cryogenic distillation, membrane separation are favored due to their advantages of low cost, high efficiency, and low energy consumption. Polymer membranes have excellent film-forming ability, processability and good mechanical properties, but there is often a restrictive balance between the permeability and selectivity of polymer membranes. Although inorganic membranes exhibit better separation performance, they are costly and difficult to process into uniform membranes. Mixed matrix membranes (MMMs), consisting of inorganic fillers dispersed in polymer mat...
