This technology addresses a critical need in the chemical industry for efficient syngas conversion to support the production of plastics and polymers. The discovery of the Fe10In/Al2O3 catalyst represents a breakthrough in converting syngas into light olefins with high selectivity (up to 45% with CO2 included) and remarkable stability (72-hour run) at 400°C and 5 bar pressure. By adjusting the Fe:In loading ratios, this catalyst achieves optimal surface composition, enhancing olefin production while minimizing methane and carbon dioxide formation. The catalyst's stability ensures consistent performance and lower maintenance costs for industrial processes. Its ability to promote C-C coupling reactions towards olefins while inhibiting methane formation underscores its effectiveness and environmental benefits. As the demand for sustainable chemical production increases, catalysts like Fe10In/Al2O3 offer a compelling solution to improve process efficiency and meet industry demands for enhanced performance and selectivity.
