20140250773 | AROMATIC HYDROCARBONS FROM DEPOLYMERIZATION AND DEOXYGENATION OF LIGNIN - Processes are disclosed that achieve a high conversion of lignin to aromatic hydrocarbons, and that may be carried out without the addition of a base. Depolymerization and deoxygenation, the desired lignin convention steps to yield aromatic hydrocarbons, are carried by contacting a mixture of lignin and a solvent (e.g., a lignin slurry) with hydrogen in the presence of a catalyst. A preferred solvent is a hydrogen transfer solvent such as a single-ring or fused-ring aromatic compound that beneficially facilitates depolymerization and hinders coke formation. These advantages result in favorable overall process economics for obtaining fuel components and/or chemicals from renewable sources. | 09-11-2014 |
