A Short Historical Review of Fast Pyrolysis of Biomass

In this short review, we survey the historical progress of fast pyrolysis technologies for thermochemical liquefaction of biomass to produce so-called "bio-oil". Our focus is on the potential applications of bio-oil as a liquid fuel for heat and power generation. We point out some of the inherent properties of bio-oil that create difficulties standing in the way of these applications. Finally, we take a brief look at some processes that aim to valorize bio-oil by conversion to higher value liquid fuel products
