Abstract
Embodiments relate generally to systems and method for processing tars to produce benzene, toluene, and xylene (BTX). A method for processing tars may comprise distilling the tars to separate creosotes and pitch; and processing the pitch via hydropyrolysis, including both hydrogenation and hydrocracking functions, to remove heteroatoms and break down polyaromatics in the pitch and produce monoaromatics, such as BTX. A system for processing tars may comprise one or more of the following: an input stream comprising tars feeding into a column; the column configured to separate the tars into one or more creosote streams and a pitch stream; and a reactor (or a series of reactors, or beds within a single reactor), wherein the pitch stream is fed to the reactor along with a stream of hydrogen, wherein the reactor is configured to break down the pitch to produce BTX.
