A QI-free coal tar pitch with a softening point around 80°C was air blown in an autoclave at 330°, 360° and 380°C, respectively, for various periods in order to prepare a pitch precursor for GPCF. Air blowing markedly increased the softening poin

Three representative isotropic pitches, coal tar pitch NP80, its hydrogenated NHP and petroleum pitch A60, were air blown at 330°C in order to study comparatively their oxidation reactivities in the preparation of isotropic pitch precursors with a h

Isotropic naphthalene and hydrogenated coal tar pitches with a lower softening point were air blown at 330°C with or without addition of 1,8-dinitronaphthalene (DNN) in order to prepare a fully isotropic pitch with a higher softening point. The soft

Coal tar mesophase pitch fibres stabilized at 270° C to different extents were carbonized under strain by the constant load or constant length, using different heating rates, and further graphitized at 2500° C. Shallow and moderate stabilization pr

Two-step stabilization, air oxidation, and solvent extraction were applied to introduce a skin-core structure in a coal tar mesophase pitch based carbon fiber. Pitch fiber was first oxidized at 270°C for short periods in air or 10% O2, successively

Stabilization of a petroleum-derived mesophase pitch (P-MP) fibers was investigated in order to create a skin-core structure in the carbonized fibers. The pitch fibers were either oxidatively stabilized at 270°C in air or 10 vol% O2 for short period

It is definite that stabilization conditions such as stabilization temperature, time, and heating rate, as well as partial pressure of oxygen, are very influential in the formation of a skin-core structure in carbonized fibers about 10 μm in diamete

Cocarbonization properties of a particular FCC decant oil (FCC-DO) of paraffinic nature with low sulfur vacuum residue (LSVR) were studied in an attempt to find guiding principles of its thermal modification for production of better quality needle co
