摘要： A novel reformed mesophase pitch having a mesophase content MC of between 40 and 100%, a quinoline-insoluble content QI of between 5 and 70 weight % and anisotropic domains forming a continuous phase. The reformed mesophase pitch is obtained by heat-treating a dormant mesophase pitch which comprises dormant anisotropic components which are partially hydrogenated, polycyclic polycondensed ring aromatic hydrocarbons derived from the mesophase of a mesophase pitch by hydrogenation of the mesophase and which are soluble in quinoline. The dormant mesophase pitch is optically isotropic in nature but, upon being subjected to shear forces in one direction, capable of being oriented in said direction. Preferably, the reformed mesophase pitch has a softening point SP in .degree.C. satisfying the following conditions:when 40 .ltoreq.MC

摘要： A heavy hydrocarbon feed stock is, after being heat-treated in a first cracking zone, is introduced into a second thermal cracking zone for obtaining a thermally cracked product and a pitch product. The second cracking zone has a plurality of cracking reactors which are connected in series, through which is successively passed the treated feed stock and to each of which is supplied a gaseous heat transfer medium to maintain the liquid phase therein at a temperature sufficient for effecting the thermal cracking and to strip the resulting distillable, cracked components from the liquid phase. The thermal cracking temperature in one reactor is so controlled as to become higher than that in its adjacent upstream-side reactor. The distillable, cracked components in respective reactors are removed overhead therefrom and separated into a heavy fraction and a light fraction, while the liquid phase in the downstream-end reactor is discharged therefrom for recovery as the pitch product. The light fraction is recovered as a light product oil, while the heavy fraction is fed to a third thermal cracking zone for obtaining a tar-containing product which is recycled to at least one of the reactors of the second thermal cracking zone together with a naphthene base heavy hydrocarbon oil.

摘要： A continuous process for the production of carbonaceous pitch, including heat-treating an aromatic heavy oil in a first thermal cracking zone for obtaining a first cracked product, and introducing the first cracked product into a second thermal cracking zone where it is thermally cracked by direct contact with a gaseous heat transfer medium to form distillable cracked components and a mesophase-containing pitch. The liquid phase in the second thermal cracking zone, including the mesophase-containing pitch, is discharged therefrom and separated into a mesophase-rich pitch and a matrix pitch having a low concentration of mesophase. The mesophase-rich pitch is recovered while at least a portion of the matrix pitch is recycled to the second thermal cracking zone. The distillable cracked components are stripped from the liquid phase in the second thermal cracking zone with the heat transfer medium, and the resulting gas phase is withdrawn overhead therefrom and then separated into a light fraction and a heavy fraction. The heavy fraction is fed to the first thermal cracking zone.
