As a major by-product of the brewing industry, distillers’ grains are produced in enormous quantities annually. Their resource utilization is a critical issue to be addressed and also an important pathway for achieving sustainable development in this industry. To improve the resource utilization level of distillers’ grains, this study prepared biochar from distillers’ grains as raw material, and fabricated mixed matrix membranes (MMMs) using the distillers’ grains biochar and Pebax 1657. The CO2 separation performance of these MMMs was investigated to enhance the high-value utilization of distillers’ grains. The results showed that compared to the pure Pebax 1657 membrane, the incorporation of distillers’ grains biochar improved the performance of the MMMs. Furthermore, the gas separation performance exhibited an upward trend with increasing doping ratio. The optimal performance was achieved at a doping ratio of 4 wt%. The best CO2 permeability and selectivity for the biochar-incorporated membrane were 124.1Barrer and 70.19, respectively, representing increases of 65.1% and 23.9% compared to the pure Pebax 1657 membrane. The distillers’ grains biochar-doped Pebax 1657 mixed matrix membranes demonstrated excellent performance for CO2 separation. %K 酒糟生物炭， %K CO2分离， %K Pebax 1657， %K 混合基质膜
