  • Advance in the Research of Coal-Tar Pitch Fuel
    Boiler Technology, 2020
    Co-Authors: Yao Sheng
    Abstract:

    Coal Tar pitch is the staple product in processing Tar,it,s yield counts for 50%~60% of Tar.Along with the enhance of the demand of environment protection,conflangating Coal Tar pitch directly was restritecl,it becames a very important problem that how to increase the extra value of Coal Tar pitch by disposiny it more deeply,Coal Tar pitch slurry fuek is a effective approach for solving this problem.In this paper,Coal-Tar pitch slurry fuel has been introduced on the bases of pitch slurry fuel.The prepare principle of Coal-Tar pitch fuel and the research advance of two fuel: Coal bitumen emulsion fuel and Coal pitch-water slurry have also been introduced.At preseat,the report of Coal Tar pitch slurry fuel is singularly,therefore,it,s recessary to inhance the research and development of this product.

  • The Study and Application of Coal-Tar Pitch Fuel
    Clean Coal Technology, 2020
    Co-Authors: Chang Hong-hong, Yao Sheng
    Abstract:

    In this paper the actuality of Coal-Tar pitch resource as well as it's application in the field fuel were ana- lyzed,meanwhile the foreground of developing Coal-Tar pitch fuel were forecasted.It is very important to machining Coal-Tar pitch in order to increase it's additional-value and the preparation of fuel oil by Coal-Tar pitch will be one of the approach of it.

  • Study on preparation process of medium temperature Coal-Tar pitch powder
    Modern Chemical Industry, 2020
    Co-Authors: Yao Sheng
    Abstract:

    The process to prepare Coal-Tar pitch powder with medium-temperature Coal-Tar pitch as raw material is studied,and the Coal-Tar pitch powder with granularity of 200 mesh or less is obtained via freezing grind and surfactant adding.The product is stable at room temperature.The influencing factors on stability and caloric value of Coal-Tar pitch powder,such as raw material freezing temperature,pulverization time,storing period and temperature,and surfactants,etc.,are also studied.

  • Pyrolysis of polycarbonate in Coal-Tar pitch
    Solid Fuel Chemistry, 2016
    Co-Authors: E. I. Andreikov, Marina G. Pervova, L. F. Safarov, Alexander V Mekhaev
    Abstract:

    The thermal degradation of polycarbonate in Coal-Tar pitch was studied. The composition of the liquid products of pyrolysis was determined with the use of gas chromatography–mass spectrometry; the modified Coal-Tar pitch and the pyrolysis residue were studied by Fourier transform IR spectroscopy, elemental analysis, and the determination of softening point, concentrations of substances insoluble in toluene and quinoline, and yields of volatile substances. Because of chemical interaction with Coal-Tar pitch, the thermal degradation of polycarbonate in Coal-Tar pitch occurs at considerably lower temperatures than destruction without a solvent with high selectivity for phenol and p -isopropylphenol. Hydrogen transfer from the Coal-Tar pitch to the polycarbonate degradation products initiates polycondensation reactions in the Coal-Tar pitch.

  • Production of petro/Coal Tar pitch by joint distillation of Coal Tar and heavy pyrolytic oil
    Coke and Chemistry, 2010
    Co-Authors: E. I. Andreikov, O. V. Krasnikova, I. S. Amosova
    Abstract:

    The properties of petro/Coal Tar pitch and distillate fractions obtained in the joint distillation of Coal Tar and heavy pyrolytic oil from ethylene production are described. The petro/Coal Tar pitch is particularly reactive in heat treatment and air-blowing. The petro/Coal Tar pitch may be used as less carcinogenic binder and impregnating electrode pitch.

  • Review of Coal Tar Preparation and Processing Technology
    Advanced Materials Research, 2012
    Co-Authors: Jun Xia Zhang
    Abstract:

    To generate Coal Tar with Coal is the key technology of Coal chemical industry, the generated Coal Tar is one of the important industry fuel and chemistry raw materials, and more attentions were attracted in Coal Tar preparation and processing technologies in recent years. Therefore, review of the updated technologies is developed at the present work. As for Coal Tar preparation technology, Coal carbonization processing and Coal hydropyrolysis are mature and has been applied to industry production. In comparison, hydrogenation of Coal Tar is just at the development. In term of Coal Tar processing technology, the present leading directions are how to manufacture clean fuel as well as phenol. Based on the status of Coal Tar preparation and processing technology, resources recycling use isn’t enough, consumptions of per ton Coal is higher, environmental pollution is serious, and deep processing technology of Coal Tar needs to be raised.

  • HYDROGEN-ACCEPTING MODIFICATION OF Coal Tar PITCH ROAD BINDER
    Journal of Fuel Chemistry and Technology, 2020
    Co-Authors: Jin Ming-lin
    Abstract:

    The change in group component of the Coal Tar pitch road binder modified by tired rubber with reaction time and its modified mechanism were studied The average structural parameters of the Coal-Tar-pitch ,solvent oil and modified road binder were calculated by Brown-Lander formula using NMR, ultimate analysis and average molecular weight Results showed that the TS(toluene soluble of the binder modified with rubber)increased from 45 0% to 61 5%,HS(heptane soluble)decreased from 27 0% to 14 4%,TIS(toluene insoluble)decreased from 28 0% to 24 1% as compared with the binder without rubber In contrast of the 1H-NMR of the group components of the rubber with those of the road binder,there were the same H pulses at δ=5 5 5 3 It was considered that the rubber,as a hydrogen donor,might take part in the modification of Coal Tar pitch and formed a new asphaltine It was the hydrogen-accepting function of the Coal Tar pitch that the quality of the Coal Tar pitch road binder was improved
