Catalytic CO2 Conversion to Transportation Fuels: A New Path to CCU |
| 초록 |
Paradigm of climate change mitigation technologies is shifting from carbon capture and storage (CCS) to carbon capture and utilization (CCU). Here we propose a new path to CCU – direct CO2 conversion to liquid transportation fuels of gasoline and diesel range by reacting with renewable hydrogen produced by solar water splitting. The highly promising and CO2-neutral CCU system is possible by our discovery of a new catalyst that produces liquid hydrocarbon (C5+) selectivity of ~65 % and greatly suppressed CH4 formation to 2-3 %, which is very similar to that of conventional CO-based FT synthesis. The catalyst was prepared by reduction of CuFeO2 and ZnFe2O4 and in-situ carburization to Hägg carbide (η-Fe5C2), the active phase for heavy hydrocarbon formation. The reference catalysts derived from bare Fe2O3, CuO-Fe2O3 mixture, and spinel CuFe2O4 are much less active and produce mainly light hydrocarbons. |
