Methods and reactors for producing a fuel are disclosed herein. In some embodiments, the method uses a biomass feedstock and alkane and/or alcohol feedstock, which can be contacted with a metal-containing catalyst to form products including a bio-oil. In some embodiments, oxygen-containing functional groups can be removed from a bio-oil using one or more zeolite thin films.
