TL;DR: In this paper, the authors describe laboratory evaluations of six alternative jet fuel candidates derived from coal, natural gas, camelina, and animal fat, three of the fuels were produced via Fischer−Tropsch (FT) synthesis, while the other three were generated via extensive hydroprocessing.

TL;DR: In this article, a single-tube heat exchanger test with pure hydrocarbons and jet fuels of widely varying critical temperature was conducted and it was found that the surface deposition decrease is insensitive to fuel critical temperature but very sensitive to residence time/heating rate.

TL;DR: In this article, a two-dimensional computational model is developed to calculate the heat and mass transport associated with a flowing fuel using a unique global chemical kinetics model, which is validated by measured experimental data obtained from a flow reactor in which ndecane and n-dodecane are mildly cracked.

TL;DR: In this article, the free-radical mechanism of oxidation and deposit formation was investigated and the results were shown to be incompatible with previous mechanisms concerning the source of deposit precursors, and it was proposed that the presence of naturally occurring antioxidant molecules plays an important role in both inhibiting the oxidation of the fuel and forming deposits.

TL;DR: In this paper, the effects of pressure on flowing, mildly cracked, supercritical n-decane were analyzed with the aid of a unique two-dimensional computational fluid dynamics model that simulates the formation of cracked products.
