    摘要： In a process for detoxifying a coal-tar deposit, effective amounts of carbon and a calcium oxide containing substance are added at a mixing station to at least a portion of the coal-tar deposit. The reaction mixture thus formed is mixed at a temperature of about 70.degree. F. to 130.degree. F. for a time sufficient to detoxify it and convert it into a non-hazardous reaction product. The coal-tar deposit may be either a substantially homogeneous coal-tar or a heterogeneous coal-tar contaminated substrate. The mixing station site may be either subsurface or surface and may include a container. The non-hazardous reaction product may be separated into small particles, suitable as fuel, and large particles, suitable as safe fill.

    摘要： This application relates to a process for making carbon artifacts from solvated mesophase pitch comprising quinoline insoluble materials. The process has a significant advantage over the art as it permits the use of otherwise unusable pitch feedstocks and the artifacts formed according to the process retain their structural integrity during carbonization. This invention also relates to the pitch formed by this process and carbon artifacts formed by this process.

    摘要： Commercially attractive continuous processes for the preparation of mesophase pitches for manufacturing high-performance carbon fibers are disclosed. One feature resides in that conversion of a pitch into a mesophase pitch is conducted continuously by using a unique continuous dispersion-heat-treating apparatus. The other feature resides in that the raw material for hydrogenation treatment which is a pretreatment preceeding to the final heat treatment for the production of a mesophase pitch, is prepared 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 the hydrogenation treatment. 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. Combination of the first and the second features, of course, can provide a better commercial success. In fact, the process of the present invention can provide a carbon fiber having a tensile strength of more than 300 kg/mm.sup.2 and a graphite fiber having a tensile strength of more than 400 kg/mm.sup.2 and a modulus of elasticity of more than 60 ton/mm.sup.2. Processes with minor modifications to the above are also disclosed.

    摘要： An asphalt composition containing an asphalt, a copolymer of an olefin with an anhydride or a nitrile, and an unsaturated elastomer having at least two terminal groups each with an active hydrogen, a halogen, an epoxy oxygen or a cyanocarbon. The composition may be prepared by copolymerizing an olefin with an anhydride or a nitrile in the presence of a free radical initiator, and thereafter mixing the copolymer with the asphalt and elastomer. The copolymer may be mixed first with a petroleum oil, then with the elastomer and lastly with the asphalt. The copolymer may be a polyanhydride from maleic anhydride and 1-octadecene and the elastomer may be a hydroxy-terminated polybutadiene.

    摘要： There is disclosed pitch prepared from petroleum pitch, which is normally considered to be inferior to coal tar pitch, which petroleum pitch has properties to equal that of coal tar pitch. That is to say, that the softening points, the Conradson carbon, the toluene insolubles and the quinoline insolubles can be matched with those obtained from coal tar pitch. In addition the properties of the petroleum pitch can be varied to meet end user specifications.

    摘要： A method of producing a precursor pitch for use in the production of carbon fibers, which comprises hydrogenating a soft or middle tar pitch to obtain a hydrogenated pitch containing no free carbon and high molecular weight components and then subjecting it to a heat treatment. In this method, the hydrogenation is carried out in the presence of tetralin at a temperature of 400.degree.-450.degree. C., and the heat treatment after the removal of solvent insoluble components and solvent is carried out in an inert gas atmosphere at a temperature of 450.degree.-500.degree. C. and under a reduced pressure of 0.1-10 Torr.
