Fischer-Tropsch liquids

The reactor operates either at low (200-240°C) or high (300-350°C) temperatures and between 1-4 MPa. The product mix changes from longer to shorter chain length molecules as the temperature increases. The product stream from a Fischer-Tropsch reactor is a mix of many components but by selecting the right operating conditions the mix can be adjusted so that the product stream has mostly diesel fuel properties.

The production of Fischer-Tropsch liquids (diesel) is today the optimal route for producing energy carriers from biomass. The FT diesel is directly applicable in the existing infrastructure and is free from sulphur and aromatics in contrast to fossil diesel. For the demonstration of integrated systems ECN focuses on two lines of development (1) large-scale dedicated installations for imported biomass and (2) small- to medium scale installations for local biomass and residues.

ATR reformer temperatures are in the range of 900-1150 °C, and the reformers with pressure between 1 and 80 bar have been designed and built so far. The ATR reactor is more compact than a steam reformer but larger than a POX unit. The main advantage of the ATR process is that it will produce a syngas with very favorable H2-to-CO ratio for downstream usage in chemical synthesis. The ratio should be 2 for Fischer-Tropsch liquids or methanol synthesis. 

The Rectisol process, developed by Lurgi, is the most widely used physical solvent gas treating process in the world. More than 100 Rectisol units are in operation or under construction worldwide. Its most prevalent application is for deep sulfur removal from syngas that subsequently undergoes catalytic conversion to such products as ammonia, hydrogen, and Fischer-Tropsch liquids.

Several different processes have been proposed for the conversion of solid organic wastes to a more usable liquid or gaseous form to be utilized as fuel or petrochemical feedstocks. Principally the commonly discussed processes involve the biological conversion to alcohols, the catalytic chemical conversion to methanol or Fischer-Tropsch liquids via a carbon monoxide and hydrogen synthesis gas, or the thermochemical formation of gases or oxygenated liquids by pyrolysis. Pyrolysis is defined as the decomposition of organic material at elevated temperatures. The process to be described uses a very special case of pyrolysis. 

No mention was made that any lubricants produced from Fischer-Tropsch liquids were utilized. However, during the period 1943 to 1945, diesel fuel used by both the Navy and Army contained FT liquids. The FT diesel oil, most of which was obtained from the Miike Synthetic Oil Plant at Omuta, was utilized by the Navy by blending with 90% of Tarakan oil, to meet diesel fuel specifications. The Army used about 50% of the FT diesel oil production as fuel for diesel engines in tanks.
