摘要： A process for an efficient preparation of a mesophase pitch is disclosed. The process is suitable for the production of high performance carbon fibers, from a coal tar or a petroleum residual oil. More particularly, the present invention relates to a process for the preparation of a homogeneous mesophase pitch which comprises a continuous thermal treatment of a heavy oil or a pitch which does not contain quinoline insoluble fractions, in the presence or absence of an aromatic oil, subsequent distillation of the thermally treated product, recovery of a pitch with extremely low quinoline insoluble contents, hydrogenation of the pitch by continuous thermal treatment in the presence of a hydrogen-donating solvent, distillation and recovery of a hydrogenated pitch, and thermal treatment of the hydrogenated pitch. The mesophase pitch prepared by the process of the present invention is suitable for the production of high performance carbon fibers.

摘要： The unwanted components from coal tars should be removed at a certain stage of the process for producing homogeneous spinning pitches which are suitable for use in the production of high-performance carbon fibers from coal tars. The unwanted components can be eliminated from coal tars in a very efficient manner by the following procedures: subjecting the coal tars to distillation or flash distillation so as to separate a heavy component having a boiling point higher than a predetermined temperature, dissolving the heavy component in a monocyclic aromatic hydrocarbon solvent, and subjecting the solution to'filtration or centrifugation.

摘要： When preparing carbon artefacts from heavy oils of petroleum or coal origin, removal of undesirable components or recovery of desirable components from raw materials or intermediates is usually required so as to improve the quality of the final products. Such removal or recovery operation is conventionally done by filtration. In the past, regeneration of filters clogged with solid carbonaceous materials inevitably formed by the filtration operations is difficult and troublesome procedures. Herein disclosed is a simple and effective process for regenerating filters clogged with solid carboneceous materials, characterized by treating the filter medium in an aqueous solution of hydrogen peroxide with heating and then optionally conducting ultrasonic washing in water or a solvent. By this simple process, clogged filters can be regenerated completely to show the same filtration performance as new filters.

摘要： A process for the preparation of an excellent mesophase pitch suitable for use as a spinning pitch for the production of high-performance carbon fibers is disclosed. The mesophase pitch can satisfy the four remarkable characteristics at the same time, i.e., a Mettler method softening point of below 310°C, a mesophase content of above 90% as examined on a polarized microscope, a quinoline insoluble content of less than 10 wt%, and a xylene soluble content of less than 10 wt%. The mesophase pitch is particularly homogeneous and is easily spinnable. The process can be characterized by using a heavy oil or pitch having substantially no BTX-insoluble material as the starting raw material, subjecting the raw material to a simple four-step treatment of (1) a continuous heat treatment in a tubular heater, (2) a distillation operation, (3) a BTX-solvent extraction and (4) a distillation operation; while recycling a soluble component obtained in the step (4) to the heat treatment of step (1) and recovering a BTX-solvent insoluble component formed in step (3) as the material for hydrogenation treatment and succeeding final heat treatment for converting into a mesophase pitch. This feature can provide a significant increase in the yield of a mesophase pitch. Furthermore, unexpectedly, the recycle of the soluble component into the heat treatment of step (1) is helpful to improve the characteristics of the ultimate products, i.e., carbon fibers or graphite fibers. The process of the present invention can provide a carbon fiber having a tensile strength of more than 2942 MPa (300 kg/mm²) and a graphite fiber having a tensile strength of more than 3923 MPa (400 kg/mm²) and a modulus of elasticity of more than 588 GPa (60 ton/mm²).

摘要： A process for the preparation of an excellent mesophase pitch suitable for use as a spinning pitch for the production of high performance carbon fibers is disclosed. The mesophase pitch can satisfy the four remarkable characteristics at the same time, i.e., a softening point of below 320°C as determined by Mettler method, a mesophase content of above 90% as examined on a polarized microscope, a quinoline insoluble content of less than 20%, and a xylene soluble content of less than 20%. The mesophase pitch is particularly homogeneous and is easily spinnable. The process can be characterized by a preliminary extraction step, a continuous heat treatment step, and an extraction step. In some cases, the preliminary extraction step can be omitted. Graphite fibers having a tensile strength of about 400 Kg/mm² and a modulus of elasticity of above 60 ton/mm² can be obtained from the mesophase pitch. Further, even carbon fibers prepared at a carbonization temperature of 1000°C have a tensile strength of about 300 Kg/mm² .
摘要翻译：公开了一种制备适合用作生产高性能碳纤维的纺丝沥青的优良中间相沥青的方法。中间相沥青可以同时满足四个显着特征，即通过Mettler方法测定的软化点低于320℃，在偏光显微镜下检测的中间相含量高于90％，喹啉不溶物含量少 20％以上，二甲苯可溶物含量小于20％。中间相沥青是特别均匀的并且易于纺丝。该方法可以通过预萃取步骤，连续热处理步骤和萃取步骤来表征。在一些情况下，可以省略初步提取步骤。可以从中间相沥青得到拉伸强度为约400Kg / mm 2，弹性模量高于60吨/ mm 2的石墨纤维。此外，即使在碳化温度为1000℃下制备的碳纤维的拉伸强度也为约300Kg / mm 2。

摘要： A preformed material for making carbon composites reinforced by short carbon fibers comprising short carbon fibers, a matrix material and a viscosity increasing agent which are homogeneously dispersed, and a process for the manufacturing the same are disclosed. The process comprises stirring and mixing said short carbon fibers and matrix material in a dispersion medium to which said viscosity increasing agent has been added, to obtain a dispersion mixture; molding the dispersion mixture; and drying the molded material to remove the dispersion medium. The preformed material comprises the short carbon fibers and the matrix material in a homogeneously dispersed state, which can be kept in a stable manner, and is easy to handle. Because of the excellent homogeneity, carbon composites reinforced by short carbon fibers which are prepared from the preformed materials have a high bending strength even if their volumetric fiber content is small.
