Carbon dioxide (CO₂) capture and utilization (CCU) plays an important role in abating carbon emissions, mitigating global warming, and converting CO₂ as feedstock to value-added fuels and chemicals. Herein, a proof-of-concept study of a novel integrated process, consisting of a membrane separator (MS) followed by a nonthermal plasma reactor (NTPR) in tandem, was presented and systematically investigated, as an efficient platform, for potential applications in CCU. Specifically, biogas upgrading via CH₄ enrichment was used as the model system to investigate the proposed integrated system (using SAPO-34 zeolite membrane in a MS and Ni/NaBETA and Ni/UiO-66 catalyst in the NTPR). Upon optimization, the hybrid MS-NTPR system showed satisfactory carbon capture efficiency (CCE) and carbon utilization efficiency (CUE) of ca. 91.8% and 71.7%, respectively. In addition, the integrated process also exhibited excellent stability for CCU in upgrading synthetic biogas with a stable performance over a 40-h longevity test. This work, for the first time, showed the feasibility of using the novel integrated process for effective CCU.

膜分离与非热等离子体催化的整合：CO ₂捕集和利用的概念证明

二氧化碳（CO ₂）的捕获和利用（CCU）在减少碳排放，缓解全球变暖以及将CO ₂作为原料转化为增值燃料和化学品方面发挥着重要作用。在此，提出了一种新颖的集成工艺的概念验证研究，该工艺由膜分离器（MS）和随后的非热等离子体反应器（NTPR）串联构成，并作为一种有效的平台进行了系统研究，可用于潜在的应用领域。 CCU。具体而言，通过CH _4进行沼气升级富集用作模型系统以研究拟议的集成系统（在MSPR中使用SAPO-34沸石膜，在NTPR中使用Ni / NaBETA和Ni / UiO-66催化剂）。经过优化后，混合MS-NTPR系统显示出令人满意的碳捕获效率（CCE）和约200的碳利用效率（CUE）。分别为91.8％和71.7％。此外，该集成过程还显示出CCU在升级合成沼气方面具有出色的稳定性，并且在40小时的寿命测试中具有稳定的性能。这项工作首次显示了使用新颖的集成流程进行有效CCU的可行性。
