Abstract
This specification discloses a process to convert a converted lignin feedstream to an aromatic composition comprised of aromatic compounds. The process follows the steps of exposing the converted lignin feedstream to at least one catalyst in the presence of donated hydrogen atoms at an exposure temperature greater than 190° C. for a time of at least thirty minutes. The donated hydrogen atoms are donated from at least one hydrogen donating compound during exposure of the converted lignin feedstream to the at least one catalyst at the exposure temperature. The resulting products are comprised largely of aromatics.
