    Abstract: A process for purifying at least one product from coal tar is described. The process involves separating a coal tar fraction having a boiling point in the range of 180°C to 230°C into an acidic portion and a non-acidic portion by contacting the fraction with a caustic compound. The acidic portion is separated into a cresol portion and a xylenol portion, and the non-acidic portion is separated into a naphthalene portion and a naphthalene co-boiler portion. The acidic portion and the non-acidic portions are separated by contacting with an adsorbent comprising small, discrete crystallites, the adsorbent having less than 10 wt% amorphous binder component. The various portions can be separated in a similar manner.

    Abstract: Disclosed is a process for producing mesophase pitch by hydrogenation of high-temperature coal tar, comprising removing salts and quinoline insolubles from the high-temperature coal tar to obtain a clear oil; using the clear oil as a hydrogenation feed oil, or pre-distilling the clear oil to obtain a bottom component with a boiling point higher than 230°C and formulating the bottom component into a hydrogenation feed oil; refining the hydrogenation feed oil by catalytic hydrogenation to obtain a refined hydrogenated oil; distilling the refined hydrogenated oil to obtain hydrogenated pitch; subjecting the hydrogenated pitch to thermal condensation polymerisation 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 being susceptible to carbon deposition and coking during the process, and not tending to block the reactor. The product has a high mesophase content, a low softening point and a low impurity content.

    Abstract: Anthracene is precipitated in improved purity and yield by cooling a creosote coal tar distillation fraction. A ketone such as acetone is added to the fraction before the anthracene precipitates. The ketone retains phenanthrene and/or carbazole in the liquid phase as the anthracene precipitates. If the ketone is then removed, the phenanthrene and/or carbazole precipitates and can also be purified.
