Abstract
The present invention relates to systems and methods for producing fuels. In an embodiment, the invention includes a method of producing a diesel-equivalent fuel, including pyrolyzing biomass to form a pyrolysis oil and contacting the pyrolysis oil and an alcohol with a metal oxide catalyst at a temperature of greater than about 60 degrees Celsius. In an embodiment, the invention includes a method of refining pyrolysis oil including contacting pyrolysis oil and an alcohol with a metal oxide catalyst at a temperature of greater than about 60 degrees Celsius. In an embodiment, the invention includes a system for processing biomass into fuel including a pyrolysis chamber defining an interior volume; a first heating element configured to heat the pyrolysis chamber; a refining chamber in selective fluid communication with the pyrolysis chamber, the refining chamber defining an interior volume, a metal oxide catalyst disposed within the interior volume; and a second heating element configured to heat the refining chamber. Other embodiments are also described herein.
