Identified Final Aliphatic/Aromatic Product Distributions, for First, Second and Third Runs (Catalyst Recycling Experiments) of the Phosphidated Ni/SiO2 Catalyst, for the Conversion of Poplar Lignin Oil to Aromatic Hydrocarbons
Run | Aromatics-Directed HDO |
|
---|---|---|
Aliphatic | Aromatic | |
1st | 22% | 78% |
2nd | 26% | 74% |
3rd | 23% | 77% |
General reaction conditions: 5 (or 0.5) MPa H2, T = 573 (or 623) K for aliphatics (or for aromatics-directed) HDO. For recycling experiments, the catalyst was washed with n-hexane, dried and then reused.
