Abstract
A process for producing pitch from pitch precursors, such as wood tar, coal tar or petroleum fractions is disclosed. Direct contact heat exchange of the pitch precursor with molten metal, preferably maintained as a metal continuous bath, heats the pitch precursor to a temperature sufficient to induce thermal polymerization reactions and produce a pitch product.
