摘要：CO_(2)-based carbon-neutral organics production processes could potentially reshape the chemical industry.However,their feasibility and net carbon footprint rely strongly on the sources of H_(2).Herein,we present a comprehensive comparative techno-economic analysis of CO_(2)-based methanol(CO_(2)TM)and aolefins(CO_(2)TO)manufacturing using various feedstock supply modes:(1)the standalone mode with external CO_(2)but H_(2)from on-site water electrolysis,(2)the integrated mode with both CO_(2)and H_(2)recovered from coal-chemical plants,and(3)the integrated mode with recycled CO_(2)but H_(2)from on-site water electrolysis.The integration of CO_(2)TM and CO_(2)TO into coal-to-olefins(CTO)and coal-to-methanol(CTM)facilities is currently cost-effective and can reduce net CO_(2)emissions by 65.7%and 68.5%,resulting in a three-fold and two-fold increase in carbon efficiency,respectively.As carbon tax policies and electrolysis technologies continue to evolve,standalone CO_(2)TM and CO_(2)TO are projected to become more economically competitive than CTO and CTM by 2035-2045.
