WebMar 10, 2006 · EELS analysis of the oxygen K edge allows us to distinguish the amorphous unreduced iron phase from the silica binder, indicating these are two separate phases. These results shed light onto the complex phase transformations that accompany the activation of iron catalysts for Fischer–Tropsch synthesis. WebThe Fischer Tropsch reactor requires a feedstock of synthesis gas (i.e. carbon monoxide and hydrogen) at pressure to generate hydrocarbon products. The resulting FT liquid fuel product is a mixture of hydrocarbons, mainly of n-paraffins of C5 to C40 in length. OxEon utilizes a two-part product collection step in which the longer hydrocarbon ...
