English
This paper proposes a CO2-assisted oxidative dehydrogenation-hydroformylation (CO2-ODH-HF) cascade for propane upgrading. By replacing conventional propane dehydrogenation with a CO2-ODH reactor, the system becomes syngas self-sufficient, eliminating external CO procurement. Aspen Plus simulations and life-cycle assessment demonstrate ~42% lower greenhouse-gas emissions and reduced total production costs compared to conventional processes. Sensitivity analyses confirm robustness against price fluctuations.

In the global GX context
Globally, this work contributes to the growing field of CO2 utilization and process intensification for decarbonizing chemical production. The cascade demonstrates how CO2 can be integrated as a reactant rather than a waste, achieving both economic and environmental benefits. It provides a scalable blueprint for carbon-efficient aldehyde synthesis, relevant to the petrochemical industry's transition to net-zero.

📄 Abstract（原文）
Propane upgrading is fundamentally constrained by the high energy demand of conventional dehydrogenation and the reliance of hydroformylation on fossil-derived syngas, limiting both efficiency and sustainability. We redesign this architecture by establishing a carbon dioxide (CO2)–assisted oxidative dehydrogenation–hydroformylation (CO2-ODH-HF) cascade that replaces propane dehydrogenation (PDH) with a CO2-ODH reactor and circulates CO2 to generate carbon monoxide (CO) and dihydrogen (H2) internally. Aspen Plus simulations show that this shift in reaction route creates a syngas self-sufficient system in which propylene formation, CO2 utilization, and hydroformylation become directly coupled. The integrated cascade enhances carbon-utilization efficiency, eliminates external CO procurement, and substantially reduces total production costs compared with PDH-HF. Life-cycle assessment further indicates ~42% lower greenhouse-gas emissions per kilogram of aldehyde produced, without triggering economic-environmental trade-offs. Sensitivity analyses reveal strong robustness against fluctuations in the feed price of liquefied petroleum gas (LPG) containing propane compounds, CO cost, and hydroformylation catalyst loss. By restructuring underlying reaction pathways and carbon flows, the CO2-ODH-HF cascade establishes a scalable and carbon-efficient route for propane upgrading and aldehyde synthesis.
