Process for removing solids from coal tar United
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
