Abstract

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.
