Supercritical fluid (SCF) extraction has been used to fractionate an isotropic petroleum pitch and produce a number of pitch fractions, many of which contain 100% mesophase. Toluene was used as the supercritical solvent, and experiments were carried out in a region of liquid-liquid equilibrium that
Liquid fuels (transport, refining, quality, storage) functionalized lipids. The formation of all sulfur compounds described in this study was explained by reaction of inorganic sulfur species with a double bond or an alcohol group. Ketones, aldehydes and carboxylic acids appear to be less effective.
