HYDROPROCESSING OF PYROLYSIS OIL AND ITS USE AS A FUEL

摘要

This invention provides low sulfur fuels, particularly low sulfur bunker fuels, comprising hydroprocessed pyrolysis oil. The hydroprocessed pyrolysis oil can be produced using a catalyst suited to processing pyrolysis oils that may be relatively high in water content and under relatively low severity conditions to limit water formation, while making the hydroprocessed pyrolysis oil more stable than prior to hydroprocessing. The pyrolysis oil can be converted to a more stable hydroprocessed product, e.g., by converting at least a majority of the aldehydes, ketones, and/or carboxylic acids in the pyrolysis oil to more highly stable compounds, such as alcohols. The hydroprocessed product can be particularly suited as a blend component for producing a variety of reduced sulfur fuels.
