It is well-known that dispersing catalysts to obtain good contact with coal particles enhances coal liquefaction. This is often accomplished using soluble catalyst precursors that are then converted to an active form. In this study, it is shown that

In “good” solvents such as pyridine, coal particles swell and fracture to some degree as soluble material is extracted, but they remain as more-or-less coherent particles. It is shown here that certain ionic liquids (ILs) are capable of solubiliz

Data is presented from the PSU flowing reactor in the 350−550 °C range that shows that jet fuel derived tube surface thermal oxidative deposit and temperature are inversely related; as fuel temperature increases tube surface deposit decreases. It

We present data that suggest that jet fuel smoke point and the formation of thermal oxidative deposit are linked by formation of a common intermediate, high molecular weight soluble macromolecular oxidatively reactive species (SMORS). Hardy and Wecht

The U.S. Air Force (USAF) has committed to use 1/1 volumetric blends of conventional jet fuels with Fischer−Tropsch (FT) derived fuels by 2016. Previous work by Balster et al. (Balster, L. M.; Zabarnick, S.; Striebich, R. C.; Shafer, L. M.; West, Z

JP-900 is a generic name representing a future jet fuel that will be required to handle the anticipated thermal stress of ∼900 °F (482 °C) for several hours. In the previous paper in this journal, we showed that the addition, to a JP-8 fuel, of m

It is anticipated that future jet fuels will be required to handle a thermal stress of approximately 900 °F (480 °C). Such an environment presents many challenges in providing fuels with the necessary thermal oxidative and pyrolytic stability. We r
