CO₂ Conversion / CO₂ Electroreduction
CO₂ conversion is the key step that transforms captured carbon dioxide into usable intermediates or fuel molecules, bridging carbon resources and the e-fuels value chain. Through electrochemical (CO₂RR) or thermocatalytic routes, CO₂ can be converted into carbon monoxide (CO) or syngas, which serve as building blocks for methanol, methane, and liquid fuel synthesis.
In engineering practice, CO₂ conversion emphasizes process controllability and system integration. By converting CO₂ into intermediates and coupling with downstream synthesis, a more stable and scalable fuel production pathway is achieved.
EPC focuses on CO₂ conversion pathways through coordinated optimization of electrolysis systems and reactor design, enabling stable conversion of CO₂ into usable intermediates and seamless integration with downstream fuel synthesis.
Engineering Pathway to Intermediates
CO₂ is first converted into stable intermediates such as CO or syngas, building a controllable and scalable fuel synthesis pathway rather than relying on direct end-product formation.
Multi-Pathway Integration & System Synergy
By combining electrochemical (CO₂RR) and thermocatalytic routes, we achieve stable CO₂ conversion across varied operating conditions. Through integrated system design and process engineering, we ensure seamless downstream alignment and flexible operation.
Carbon Capture
Carbon capture is the critical step that separates, purifies, and recovers CO₂ from industrial emissions or ambient air. It serves as the entry point connecting carbon emissions to resource utilization. In the e-fuels and carbon cycling system, CO₂ is not merely a waste stream but a valuable feedstock for conversion and utilization.
Depending on the application, CO₂ can be sourced from industrial tail gas (e.g., chemical, steel, cement plants) or from direct air capture (DAC). These sources differ significantly in concentration, impurity profiles, and fluctuation characteristics, posing varying requirements for capture processes, purification trains, and system stability.
In engineering practice, carbon capture is more than a separation step. It involves gas pretreatment, impurity removal, concentration enhancement, pressure and flow regulation, and more. The core objective is to provide a stable, continuous, and controllable CO₂ supply for downstream conversion. System performance depends not only on capture efficiency but also on energy consumption control, operational stability, and integration with downstream processes.
EPC takes an engineering-centric approach to carbon capture system design and integration along the "electricity–hydrogen–carbon" pathway. Through gas treatment and process optimization, we transform CO₂ from an emission source into a reaction feedstock. Coordinated design with hydrogen production and CO₂ conversion systems enables stable coupling across subsystems, driving the practical utilization of carbon resources.
Multi-Source CO₂ Capture & System Adaptability
Our capture systems support diverse CO₂ sources including industrial tail gas and ambient air. We ensure stable, consistent supply and seamless integration with downstream conversion processes.
System-Integrated Stable Supply Capability
Through gas treatment and process optimization, CO₂ is delivered continuously and consistently to meet the feedstock stability requirements of downstream conversion and fuel synthesis.
