Researchers from the Beijing Institute of Low Carbon Clean Energy and other institutions have collaborated to develop a new catalytic technology. They succeeded in directly producing high-grade chemical linear alpha olefins from synthetic gas converted and produced from coal, natural gas or biomass.
The researchers have come up with a new approach that is different from traditional iron oxide catalysts, establishing a pure-phase iron carbide catalyst system with high carbon efficiency, low carbon dioxide, and high activity.
The new technology produces 80% less carbon dioxide than existing technologies, and the alpha-olefin yield is more than 100 times that of existing technologies at the same reaction temperature. In addition, the production of alpha-olefins can be achieved at conditions of 250-290°C, paving the way for large-scale industrial production of linear alpha-olefins.
