ARGE fixed bed process

In the ARGE fixed bed process Idgh boiling fractions and waxes are mainly obtained [4J, Under the same curidiliuns, sintered iron catalysts yield mainly hydrocarbons in the gasoline and diesel range. This can be explained by their lower specific surface area, pore volume and specific activity. Of the three catalyst types, (he fused iron catalyst Is characterized by the lowest specific surface area, pore volume and activity and is thus operated at higher temperatures. 

Figure 6.11.12 shows a classical commercial Fischer-Tropsch plant, the so[Pg.675]

For modeling and simulation of a Fischer-Tropsch reactor we use the classical ARGE fixed bed process with Fe as catalyst. The recycle ratio is 2.5. Table 6.11.3 lists the other reaction conditions. Although the ARGE FT process may not be the most modern FT process it is the only one for which reUable data on the process as well...
