To assess the potential advantages of this method, three catalytic fast pyrolysis oils—produced with HZSM-5 at biomass-to-catalyst ratios from 0.5 to 2.1 and having oxygen contents from 3 to 18%—and a non-catalytic oil containing 28% oxygen, were hydrotreated in a batch autoclave with CoMo(S) at 330-420°C and 2500 psig total pressure.
Multiple catalytic-oil and temperature conditions produced products with oxygen contents about 1% by weight. Hydrogen consumption was less than ½ that of the non-catalytic oil. GC-MS analysis showed high concentrations of aromatics and hydrogenated aromatics. Phenols were the main oxygenated compounds detected in the products. The low-oxygen products and lower hydrogen consumption show that this is a promising alternative.
