Nano-Engineered Co-Ionic Ceramic Reactors for CO2/H2O Electroconversion to Light Olefins

作为全球二氧化碳排放的主要贡献者，商品化学工业应立即与可再生电力相结合，以摆脱化石燃料资源。ECOLEFINS旨在建立一种新的全电动模式，用于将CO2和H2O电转化为轻质烯烃，聚合物和其他日常生活化学产品的关键中间体。所提出的概念将与石油基轻烯烃生产相关的大量CO2排放逆转为大量CO2捕获和对负碳乙烯、丙烯和丁烯的稳定化。该概念引入了共离子陶瓷膜反应器和短堆/模块，其将阳极蒸汽电解制氢与阴极CO2电解和加氢转化为轻烯烃，通过定制和纳米工程电极;旨在开发一种更有效的技术，用于单步RES动力的CO2人工光合作用，以获得有价值的化学品。这一雄心需要多学科的任务，需要在以下领域的前沿研究之间高度协调的协同作用：i）共离子复合材料、钙钛矿前溶液和有机金属的先进材料科学与工程，ii）电化学和电化学过程工程，iii）催化科学与工程，iv）计算机辅助材料设计和原子尺度建模，以及v）数字化真实规模流程建模和经济评估，沿着全面的可持续性评估、影响框架的应用社会研究以及市场化规划。

As a major contributor to the global CO2 emissions, the commodity chemical industry should be urgently coupled with renewable electricity to become independent from fossil fuel resources. ECOLEFINS aims to establish a new, all-electric paradigm for the electro conversion of CO2 and H2O to light olefins, the key-intermediates for polymers and other daily life chemical products. The proposed concept reverses the heavy CO2 emissions associated to the petroleum-based light olefins production to massive CO2 capture and valorisation for carbon negative ethylene, propylene and butylene. The concept introduces co-ionic ceramic membrane reactors and short stacks/modules that merge the anodic steam electrolysis for hydrogen production with the cathodic CO2 electrolysis and hydrogenation to light olefins, over tailored and nano-engineered electrodes; aiming to develop a substantially more effective technology, for the single step, RES-powered artificial photosynthesis of CO2 to valuable chemicals. This ambition entails a multi-disciplinary task, requiring highly tuned synergies among cutting edge research in the fields of: i) advanced materials science & engineering for co-ionic composites, perovskite ex-solutions, and organometallics, ii) electrochemistry and electrochemical process engineering, iii) catalysis science and engineering, iv) computer aided materials design and atomic scale modelling, and v) digital real-scale process modelling and economic evaluation, along with a comprehensive sustainability assessment, applied social research for impact framing, and marketization planning.
