Abstract
Described herein are systems and methods for the catalytic deoxygenation of lignin to generate low-oxygen aromatics that may be useful as a sustainable aviation or marine fuel. The provided systems and methods may be performed continuously without the need for a solvent, increasing both efficiency and cost effectiveness.
Claims19
A method comprising:
- providing a reactant comprising lignin and hydrogen;
- partially deoxygenating the reactant in the presence of a first catalyst at a first temperature, thereby generating an intermediate;
- deoxygenating the intermediate in the presence of a second catalyst at a second temperature, thereby generating a product comprising aromatic hydrocarbons.
A reactor comprising:
- a first reaction zone comprising a first catalyst at a first temperature;
- a second reaction zone comprising a second catalyst at a second temperature;
- where in the reactor is capable of performing hydrodeoxygenation of lignin to generate aromatic products.
A catalyst comprising Mo2C, wherein the catalyst is capable of converting lignin to aromatic compounds at a yield greater than or equal to 80%.
