Catalysis in the Refining of Fischer–Tropsch Syncrude
There are meaningful differences in composition between Fischer–Tropsch syncrude and conventional crude oil. These differences influence the catalysis, catalyst selection and refining technologies that can be used. Some catalysts are particularly well suited for the conversion of Fischer–Tropsch syncrude, wereas some catalysts and conversion processes that are ubiquitous in crude oil refining are not. Conversion technologies relevant to Fischer–Tropsch fuel refineries, but that have not yet been covered in detail, are discussed: catalytic reforming, aromatic alkylation, alcohol dehydration and etherification. A short discussion is included on Fischer–Tropsch related oxygenate conversions that resolve specific FT refining challenges, but have not yet found their way into conceptual refinery designs.
