Definitions

  • the present invention provides a method for removing quinoline-insoluble matter from extracted tar (hereinafter simply referred to as “quinoline
  • out-of-head tar refers to a component which is obtained by distilling a coal tar and having a point lower than the degree of action at the time of arrest and separation. What did you do?
  • QI which is a consumable in the coal tar
  • the QI component is a carbonaceous particle having a diameter of 0.3 ia or less, and when contained in a large amount in the coal tar, the mesophase (sphere) is formed in the mature process of the coal tar. It is believed that it adheres to the surface of S) to prevent coalescence of the spheres S and impairs the smooth growth of spherulites.
  • the inventor of the present invention has conducted various studies to solve or eliminate the above-mentioned problems of the conventional method, and as a result, has found that a call-tar-based light can be added to the extracted tar or the ring-extracted tar. It was found that the QI component was easily and efficiently separated by subjecting the s-compound to which the medium oil was added to sa centrifugation. Around this time, it was completed based on these findings.
  • the solvent is made of coal tar, so the oil recovered by centrifugal sea bass steaming consists only of the coal tar and can be used effectively. It is. Furthermore, it is not necessary to conceal the sedimentation phase g and does not need a large amount of ripening energy for the steam S. In addition, a remarkable effect is obtained in that the yield of tar and pho or pit is remarkably high.
  • the exfoliated tar obtained by steam SB of the coal tar is subjected to centrifugal sea bass under the conditions of 100 to 400.
  • the S degree at the time of centrifugation is more preferably 200 to 350.
  • various types of concealment that can be operated within the above-mentioned a degree range can be used.
  • the centrifugal force is usually
  • the removal rate of QI may be appropriately determined according to the properties of the tar when the raw material is removed, the type of the final product, and the like. For example, in order to obtain a raw coke raw material from a head with a QI content of 3.596, the QI content removal rate is preferably 90% or more, and a carbon fiber raw material is obtained. For this purpose, it is preferable that the QI component removal rate be 9 596 or more. If necessary, the clarified liquid after the stern is steamed according to a conventional method, and then further processed to obtain a final product.
  • coal-tar light-medium oil it is possible to add a coal-tar light-medium oil to the tar at the time of removal.
  • the viscosity of 9 ⁇ tar drops not only can the operation severity be reduced to 80 to 300, but also the QI removal effect by centrifugation is improved. It will be possible to do so.
  • the coal-tar light-medium oil to be used include creator oil, naphthalene oil, and anthracene oil having a boiling point of about 80 to 350. It is preferable to use about 20 to 200 parts by weight of the coal tar-based light / medium oil per 100 parts by weight of the extracted tar. More preferably, it is about 50 parts by weight.
  • the desired raw material for carbon material can be obtained in S yield, and the coal tar oil is recovered. .
  • the recovered oil can be used again as an added oil to the exfoliation tar.
  • it is more preferable to set the operating temperature during centrifugation to 100 to 250.
  • the oil collected by the centrifugal shunter steam S consists solely of a coal tar system, and is effectively used as it is.
  • Centrifugal separator capacity is 1 2, rotation speed 4 60.0 rpsi, centrifugal force
  • the centrifugal separator used was a multifilament centrifugal extractor equipped with four 500 W capacity containers, with a rotation speed of 3000 mm fiber, a centrifugal force of 1300 G, and a processing time of 10 min. .
  • the centrifugal separation machine used the multi-spin centrifugal stern used in 3 ⁇ 43.
  • the operating conditions were as follows: rotation speed: 3 000 rp, centrifugal force: 1300 G »80 degrees, processing time: 3 ⁇ 41 It was 0 minutes.
  • the eccentric centrifugal separator As the eccentric centrifugal separator, a horizontal centrifugal centrifugal separator with a holding volume of 40 e was used, the rotation speed was 300,000 rpa, and the centrifugal force was 2,280 G. The throughput was 1 ton / hr. a
