Utilizing CO₂ in an electro-chemical process and synthesizing value-added chemicals are amongst the few viable and scalable pathways in carbon capture and utilization technologies. CO₂ electro-reduction is also counted as one of the main options entailing less fossil fuel consumption and as a future electrical energy storage strategy. The current study aims at developing a new electrochemical platform to produce low-carbon e-biofuel through multifunctional electrosynthesis and integrated co-valorisation of biomass feedstocks with captured CO₂. In this approach, CO₂ is reduced at the cathode to produce drop-in fuels (e.g., methanol) while value-added chemicals (e.g., selective oxidation of alcohols, aldehydes, carboxylic acids and amines/amides) are produced at the anode. In this work, a numerical model of a continuous-flow design considering various anodic and cathodic reactions was built to determine the most techno-economically feasible configurations from the aspects of energy efficiency, environment impact and economical values. The reactor design was then optimized via parametric analysis.

在电化学过程中利用CO ₂和合成增值化学品是碳捕获和利用技术中少数可行且可扩展的途径之一。CO ₂电解还原也被认为是减少化石燃料消耗的主要选择之一，也是未来的电能存储策略。当前的研究旨在开发一种新的电化学平台，该平台通过多功能电合成和生物质原料与捕获的CO _2的综合共增值生产低碳的e-biofuel 。用这种方法，CO ₂在阴极处还原的二氧化硫产生直接注入的燃料（例如，甲醇），而在阳极产生增值的化学品（例如，醇，醛，羧酸和胺/酰胺的选择性氧化）。在这项工作中，建立了考虑各种阳极和阴极反应的连续流设计的数值模型，以确定从能源效率，环境影响和经济价值等方面最技术经济可行的配置。然后通过参数分析优化反应器设计。
