摘要： A high strength, high modulus pitch-based carbon fiber has a crystalline structure in which the presence of the (112) cross-lattice line and the resolution of the diffraction band into the (100) and (101) diffraction lines, which indicate the three-dimensional order of the crystallite of the fiber, are not recognized, and in which the orientation angle (.phi.) of X-ray structural parameter is not greater than 12.degree. and the stack height (Lc) ranges between 80 and 180 .ANG.. The carbon fiber also has a single-fiber diameter of 5 to 12 .mu.m, tensile strength not lower than 3.0 GPa, tensile elastic modulus not smaller than 500 GPa and elongation not smaller than 0.5%.

摘要： The present invention relates to a high elongation, high strength pitch-type carbon fiber which has an improved handleability. The carbon fiber of this invention has a crystalline structure arranged in such a manner that the angle (.phi.) is 24.degree.-38.degree.; the stack height (L.sub.c) is 19-35 .ANG.; and, the interlayer spacing (d.sub.002) of the X-ray structural parameter is 3.45-3.50 .ANG.. The atomic ratio of oxygen to carbon on the surface of the fiber measured by X-ray photoelectron spectrometry is 0.1-0.35. The total oxygen content in the fiber is 0.01-0.2 wt. %; and, the elongation is 1.0% or more. The high elongation, high strength pitch-type carbon fiber prepared in accordance with the present invention can be used, for example, as a reinforcing fiber for light-weight structural material employed in the aerospace, automotive and architectural industries.

摘要： Dewaxing aid used in a solvent dewaxing process is recovered in wax bottoms from slack wax by vacuum distilling the slack wax to about 5-10 wt. % bottoms at a temperature no greater than about 320.degree. C. The dewaxing aid-containing wax bottoms is recycled back into the dewaxing process by adding same to the wax-containing oil feed in an amount ranging from about 0.5-5 wt. %. This has been found to be particularly advantageous when the dewaxing aid is an .alpha.-olefin copolymer, a chlorinated paraffin/naphthalene condensation product and mixture thereof because of their thermal stability.

摘要： A process for manufacturing a carbon fiber or graphite fiber includes melt-spinning a carbonaceous pitch, infusibilizing the resulting pitch fiber, carbonizing, and when necessary graphitizing the fiber. A precursor of the carbonaceous pitch is centrifuged in a molten state to separate the precursor pitch simultaneously into a solids slurry layer, an optically isotropic phase, and an optically anisotropic phase, and the latter is utilized as the carbonaceous pitch.
