Abstract:
A method for producing a substantially paraffinic Fischer-Tropsch product comprising at least one oxygenated species, the method comprising the steps of:(a) selecting a concentration of oxygenated species in the substantially paraffinic Fischer-Tropsch product; (b) performing a Fischer-Tropsch synthesis to provide a Fischer-Tropsch product stream; (c) isolating a substantially paraffinic product stream comprising oxygenated species from the Fischer-Tropsch product stream; (d) purifying the substantially paraffinic product stream to remove a portion of oxygenated species to provide a substantially paraffinic Fischer-Tropsch product comprising at least one oxygenated species; (e) monitoring the substantially paraffinic Fischer-Tropsch product for concentration of oxygenated species by GC-AED; and (f) adjusting the conditions of the purification of step (d) to ensure that the concentration of the oxygenated species in the substantially paraffinic Fischer-Tropsch product complies with the selected concentration.
