%X 我国是农业大国，作为农业生产中的副产物，秸秆年产量巨大，提高秸秆的高值化利用将有利于农业生产的可持续发展。本研究以小麦秸秆为原材料制备了秸秆生物炭，使用小麦秸秆生物炭和Pebax 1657制备了混合基质膜，研究了该混合基质膜分离CO2的性能。研究表明，小麦秸秆生物炭具有高比表面积、丰富的微孔结构以及较为丰富的官能团。Pebax 1657中掺杂4 wt%小麦秸秆生物炭所制备的混合基质膜具有最佳的CO2分离性能，CO2分离渗透系数和选择性分别为106.5 Barrer和74.8，相比未掺杂前的纯Pebax 1657膜分别提升了34.0%和18.0%。
China is an agricultural country, and straw, as a by-product of agricultural production, has a substantial annual output. Enhancing the high-value utilization of straw will contribute to the sustainable development of agricultural production. In this study, wheat straw biochar was prepared from wheat straw, and a mixed matrix membrane was prepared with wheat straw biochar and Pebax 1657. The performance of mixed matrix membranes for separating CO2 was investigated. The results indicated that wheat straw biochar has high specific surface area, rich microporous structure, and abundant functional groups. The mixed matrix membrane prepared with 4 wt% wheat straw biochar doped in Pebax 1657 exhibited the best CO2 separation performance. The CO2 separation permeation coefficient and selectivity were 106.5 Barrer and 74.8, respectively, which were 34.0% and 18.0% higher than the pure Pebax 1657 membrane before doping, respectively.
