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，商品化工行业迫切需要与可再生电力相结合，以摆脱对化石燃料资源的依赖。ecolfins旨在建立一种新的全电模式，用于将CO2和H2O电转化为轻质烯烃，轻质烯烃是聚合物和其他日常化工产品的关键中间体。提出的概念将与石油基轻烯烃生产相关的大量二氧化碳排放转化为大量二氧化碳捕获和碳负的乙烯、丙烯和丁烯的增值。该概念引入了共离子陶瓷膜反应器和短堆/模块，通过定制和纳米工程电极，将用于制氢的阳极蒸汽电解与阴极二氧化碳电解和加氢结合在一起；旨在开发一种实质上更有效的技术，用于单步，res驱动的二氧化碳人工光合作用到有价值的化学物质。这是一项多学科的任务，需要在以下领域的前沿研究之间进行高度协调的协同作用：1)共离子复合材料、钙钛矿前溶液和有机金属材料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，v)数字实尺度过程建模和经济评估，以及综合可持续性评估，影响框架应用社会研究和市场化规划。

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.
