DOI: 10.1002/cctc.201700792
Abstract: The Fischer–Tropsch synthesis to lower olefins (FTO) is a desirable nonpetroleum‐based route to produce basic chemicals. A novel two‐step method was applied to synthesize iron‐based supported catalysts, which is to prepare nano‐Fe3O4 first by thermal… read more here.

DOI: 10.1002/cctc.201800488
Abstract: The Fischer−Tropsch synthesis (FTS) is a non‐petroleum‐based alternative route, which directly produces fuels and value‐added chemicals (e. g. lower olefins) from coal‐, biomass‐ or natural gas‐derived syngas. The ϵ‐iron carbide, such as Fe2C, has been predicted… read more here.

DOI: 10.1002/cctc.202100270
Abstract: The conversion of synthesis gas to hydrocarbons in the Fischer‐Tropsch (FT) synthesis suffers from a broad product distribution not directly providing high fuel quality. This work, therefore, aims at bifunctional catalysts combining the FT and… read more here.
