    摘要： A process for producing mesophase pitch from high-temperature coal tar comprises: removing salts and quinoline insoluble fraction from a high-temperature coal tar to obtain a decant oil; using the decant oil as a hydrogenation feedstock, or pre-distilling the decant oil to obtain a residue with a boiling point higher than 230 and formulating the residue into a hydrogenation feedstock; catalytic hydrorefining the hydrogenation feedstock to obtain a hydrofined oil; distilling the hydrofined oil to obtain hydrogenated pitch; and subjecting the hydrogenated pitch to the thermal polymerization to obtain the mesophase pitch. The process has features such as an easily controllable degree of hydrogenation, complete removal of impurities, good raw material flowability, not tending to form the carbon deposition and the coking during the process, and not tending to jam the reactor. The product has a high content of mesophase pitch, a low softening point and a low impurity content.

    摘要： The present invention is a separation method and system in which granulation of coupled post-extraction asphalt residue is used to achieve deep separation of heavy oil. A dispersion solvent is introduced into the asphalt phase after separation by solvent extraction and the asphalt phase undergoes rapid phase change in a gas-solid separator and is dispersed into solid particles while the solvent vaporizes, resulting in low temperature separation of asphalt and solvent with adjustable size of the asphalt particles. The separation method of this invention also includes a three-stage separation of heavy oil feedstock, in which the deasphalted oil phase separated from heavy oil is treated with supercritical solvent and results in the further separation of the resin portion of the deasphalted oil, maximizing the yield and quality of the deasphalted oil. The processes and systems in this invention use atmospheric pressure and a low temperature gas-solid separator instead of a high temperature and high pressure furnace and do not require the feed pre-heating or heat exchange equipment at the inlet of resin separator column, resulting in a simplified process flow and reduced investment.
