Methods for preparing fuel compositions from renewable sources, and related systems

摘要

A method for producing a fuel composition from a feedstock which may contain biomass and municipal solid waste is described. The method includes the step of pyrolyzing the feedstock in the presence of a transition metal, using microwave energy, so that the level of oxygen in at least one product of the pyrolysis is reduced. An integrated process is also described, in which the transition metal can be regenerated. Moreover, pyrolysis products such as bio-oils can be upgraded to liquid fuel compositions. Related systems for producing fuel compositions are also described.
