The goal of this research was to oxidize lignin into aromatic chemicals via catalytic oxidation. The objectives were to: (1) investigate niobium-based catalysts for oxidation of lignin (2) test the activity of the catalysts during oxidization of lignin into aromatic chemicals (3) optimize the process parameters, and (4) investigate mechanism involved in the breakdown of lignin. The research was carried out in three phases. (Abstract shortened by ProQuest.). |
