Cold flow properties have historically been important for diesel and jet fuels. Reflecting the importance of cold flow properties, several standards have been developed to characterize pour point, cloud point, and filterability. An emphasis on characterizing fuels based on standard testing methods has led to large amounts of data that describe how fuels perform but very little published data that describe what is happening at the molecular level and to the composition of fuels. Motivated by a desire to have an improved understanding of the cold flow behavior of Fischer-Tropsch fuels, an experimental method was developed to provide easy acquisition of data on the changing compositions of liquid and solid phases as Fischer-Tropsch and diesel fuels traverse cloud point, pour point, and additive-enhanced pour point temperatures.
