ABSTRACT:
A process for removing solids from coal tar for the preparation of a coal tar pitch containing liquid comprising (1) centrifuging the coal tar at a suitable viscosity to separate a large particle size solids fraction from a first liquid fraction containing pitch and small particle size solids, and (2) filtering the large particle size fraction while maintaining the solids fraction at a suitable viscosity to thereby produce a second pitch containing liquid fraction which is substantially free of solids, and a densified readily handleable large particle size solid material. The liquid fractions are useful for making electrodes, needle coke or carbon fibers whereas the densified solid material is readily utilized.
