A comparative study of straw, perennial grasses and hardwoods in terms of fast pyrolysis products

► Thermochemical properties of biomass in terms of fast pyrolysis products were compared. ► Crops selected for this study were: straw, perennial grasses and hardwoods. ► Bio-oil from switch grass has the highest potential for the production of chemicals. ► Switch grass gives the highest yields of levoglucosan and furfural. ► Willow SRC is also an attractive energy feedstock for fast pyrolysis processing.
