Olefins are key building blocks to manufacture a wide range of value-added products such as polymers, lubricants, plasticizers, drugs, detergent and cosmetics.
Catalytic performance for direct syngas conversion to olefins. a Comparison of catalytic performance among Na-Ru/SiO 2 and other previously reported catalysts. (a: C 2–4 = selectivity). b Detailed product distribution (including CO 2 ) and ASF distribution of hydrocarbons over Na-Ru/SiO 2 catalyst. c Product selectivity, CO conversion and olefins yield at different H 2 /CO ratios in syngas over Na-Ru/SiO 2 catalyst at 533 K, 3000 mL·g cat. −1·h−1, and 1.0 MPa. d Product selectivity, CO conversion and olefins yield at different space velocities over Na-Ru/SiO 2 catalyst at 533 K, H 2 /CO ratio of 2 and 1.0 MPa. e Stability test for Na-2%Ru(P)/SiO 2 catalyst. f Reaction rate of CO and product selectivity at different Na/Ru molar ratios. Reaction conditions: 533 K, 1.0 MPa, 3000 mL·g cat. −1·h−1, H 2 /CO ratio of 2. Credit: Nature Communications (2022). DOI: 10.1038/s41467-022-33715-w Syngas conversion serves as a competitive strategy to produce olefins from nonpetroleum resources. However, the…
