    摘要: A process for producing a pitch which can be utilized as a raw material for producing carbon fibers is disclosed. The process involves distilling a petroleum heavy residual oil under reduced pressure to produce a reduced pressure distillation residual oil or a reduced pressure distillate oil. The distillation residual oil is subjected to a solvent deasphaltening treatment to produce a solvent deasphaltened oil. The solvent deasphaltened oil or the reduced pressure distillate oil is subjected to solvent extraction to obtain a solvent extraction component. The solvent extraction component is thermally modified to produce the pitch. The pitch can be utilized in a melt-spinning process in order to produce carbon fibers having desirable characteristics.

    摘要: A process for producing a pitch used as a raw material for producing carbon fibers is disclosed. The process comprises the steps of carrying out catalytic cracking of a hydrogenated residual oil prepared by hydrogenation treatment of a petroleum heavy residual oil or a mixture composed of said hydrogenated residual oil and a hydrogenated distillate oil which is prepared by hydrogenation treatment of a reduced pressure distillate oil prepared by reduced pressure distillation of the petroleum heavy residual oil. The resulting cracking oil is then destilled to produce a high boiling point fraction having a boiling point of 300°C or more. The fraction is then subjected to thermal modification. The pitch is then utilized to produce carbon fibers which have desirable characteristics. The process is advantageous in that it makes possible the use of a wide variety of different types of oils in order to produce a pitch which can be utilized in producing carbon fibers having desirable characteristics.
