Trace Additive Cleans Up Fischer-Tropsch Synthesis
A dash of bromomethane curbs carbon dioxide emissions from an industrial process used to make olefins from syngas.
By Mark Peplow, special to C&EN, the latest chemistry news includes important research advances.
Fischer-Tropsch Process
For almost a century, the industrial Fischer-Tropsch (FT) process has been used to convert syngas—a blend of carbon monoxide and hydrogen—to liquid hydrocarbons.
Breakthrough Discovery
Researchers in China have discovered that adding a trace of bromomethane to syngas can almost eliminate unwanted carbon dioxide emissions from the process while increasing the output of valuable olefins.
According to the study published in Science (2025, DOI: 10.1126/science.aea1655), this innovation has the potential to significantly reduce the environmental impact of the FT process.
