Using Biomass Gasification Mineral Residue as Catalyst to Produce Light Olefins from CO, CO2, and H2 Mixtures

The Front Cover shows a coarse solid residue particle, originating from the gasification of biomass, which acts as a solid catalyst to produce high-value chemicals, such as olefins, from mixtures of H-2, CO, and CO2. The heart of the developed catalyst material are nanoparticles, consisting of iron carbides and iron metal, together with some alkali elements, such as sodium and potassium. The latter elements act as promotors to boost the production of light olefins. This approach represents an elegant example illustrating how we can apply the concept of materials circularity, in which a waste material is transformed into a functional catalyst material.
