Seven oligomeric fractions of well-defined composition and molecular weight distribution were generated via supercritical extraction from an isotropic petroleum pitch (M-50) and used as precursors for the production of activated carbon fibers. Both i

A commercially produced petroleum pitch (M-50) consisting of PAH oligomers was fractionated via supercritical (SC)/dense-gas extraction, using two packed columns operating in series on a continuous basis. In the 1st column, toluene was used as the SC

Liquid–liquid equilibrium (LLE) phase behavior was investigated for the binary iodine–water (I 2 –H 2 O) and the ternary iodine–hydroiodic acid–water (I 2 –HI–H 2 O) at the elevated temperatures and pressures of interest for the reactiv

Packed-column supercritical extraction (SCE), followed by low-pressure gas stripping, was used to produce a dimer-rich pitch fraction from an oligomeric petroleum pitch, Marathon M-50, of broad molecular weight distribution (MWD). Both solvent-to-pit

The separation of petroleum pitch into its oligomeric fractions via dense-gas extraction (DGE), followed by the application of both new and conventional analytical techniques to those fractions, has given us unique capabilities for identifying both t

Dense-gas extraction of M-50 petroleum pitch with the solvent toluene was carried out in a continuous, countercurrent-flow, packed column at temperatures from 330° to 380°C, pressures from 42 to 84 bar, and a solvent-to-pitch ratio of 5:1. Both one

Dense-gas extraction (DGE) was used to fractionate an isotropic petroleum pitch (number-average molecular weight M n = 516) into oligomeric cuts. A countercurrent-flow packed column was used to effect the separation, with supercritical toluene being
