English
This work proposes a product-driven CCU concept where CO2-derived cyclic carbonates serve sequentially as physical CO2 absorbent and reaction medium, eliminating intermediate solvent regeneration. Experiments with [bmim]I catalyst and COSMO/Aspen simulation plus LCA show competitive energy demand and CO2 emissions while avoiding deep vacuum operation.

日本のGX文脈において
日本はCCUSをGX推進戦略の重点分野と位置づけ、製油所・化学プラントでの実装を進めている。本コンセプトは省エネ型CCUとして、国内のカーボンリサイクル実証やGXリーグ企業の脱炭素技術ポートフォリオに示唆を与える。
In the global GX context
Globally, CCU is a key pillar of industrial decarbonization under net-zero pathways. This product-driven approach addresses the energy penalty of conventional capture-regeneration, offering a scalable route for cyclic carbonate production that can be integrated into chemical value chains and reported under emerging ISSB/CSRD climate metrics.

📄 Abstract（原文）
Abstract There is an urgent need to develop energy-efficient solutions for CO2 capture and utilization, because current integrated processes remain limited by the compatibility of the capture and conversion stages. This work proposes a novel product-driven carbon capture and utilization concept, in which the CO2-derived cyclic carbonate product is sequentially employed as a physical CO2 absorbent and subsequently as the reaction medium for its own synthesis, eliminating the intermediate solvent regeneration step. Density, viscosity, and CO2 solubility were experimentally determined for four cyclic carbonates, while cycloaddition reactions were performed under representative integrated process conditions using the ionic liquid [bmim]I as a catalyst. The complete process for natural gas purification was evaluated through conductor-like screening model (COSMO)-based/Aspen process simulation and life cycle assessment. Experimental and computational results demonstrate that propylene, butylene, and hexylene carbonates provide competitive CO2 absorption performance, extending the applicability of the proposed concept to other CO2-derived cyclic carbonates. More importantly, the direct use of the CO2-rich cyclic carbonate stream as the reaction medium was experimentally validated without significant thermodynamic or kinetic limitations despite the high product concentration. The proposed concept achieves a competitive energy demand and CO2-related emissions while avoiding deep vacuum operation and intermediate solvent regeneration.
