The integration of carbon dioxide (CO2) capture and conversion processes presents an opportunity to reduce energy and capital costs required to create useful products from dilute CO2 streams, such as air or flue gas. In an integrated system, regeneration of the CO2 capture media is achieved directly through the conversion of CO2 to value-added products, eliminating dedicated CO2 desorption and compression steps. We define processes that integrate CO2 capture and CO2 conversion without going through a purified CO2 intermediate stream as “reactive capture.” In this perspective, we propose that the value proposition for reactive capture is the reduction of energy intensity and capital expense in the production of CO2-derived chemicals and materials. We describe the current strategies and the state of technology for reactive capture and provide a roadmap to guide research toward realizing these potential benefits.

反应性 CO2 捕获:碳管理过程整合的前进之路

二氧化碳 (CO 2 ) 捕获和转化过程的整合为降低从稀释的 CO 2流(例如空气或烟道气)中生产有用产品所需的能源和资本成本提供了机会。在集成系统中,通过将 CO 2转化为增值产品直接实现 CO 2捕获介质的再生,从而消除了专门的 CO 2解吸和压缩步骤。我们定义了集成 CO 2捕获和 CO 2转化的过程,无需经过纯化的 CO 2中间流作为“反应性捕获”。从这个角度来看,我们提出反应捕获的价值主张是降低 CO 2衍生化学品和材料生产中的能源强度和资本支出。我们描述了反应捕获的当前策略和技术状态,并提供了指导研究实现这些潜在好处的路线图。
