Energy & Fuels, 2014
The fuel properties of fast pyrolysis bio-oils differ significantly from those of fossil fuels. As transportation fuel, bio-oil is not suitable without upgrading because of its relatively low energy content, high water content, acidity, and poor storage stability. Upgrading of bio-oil has usually been done by treating the whole oil in a reactor.

Stability of fast pyrolysis bio-oils is a complex phenomenon, especially as numerous compounds with different reactivities are involved. Acid-catalysed condensation and polymerization reactions of carbonyl compounds and reactive lignin-derived radical species take place which increase the share of water-insoluble compounds, average molecular weight and

Transformation of Bio‐oil into BTX by Bio‐oil Catalytic Cracking
Chinese Journal of Chemical Physics, 2013Production of benzene, toluene and xylenes (BTX) from bio‐oil can provide basic feedstocks for the petrochemical industry. Catalytic conversion of bio‐oil into BTX was performed by using different pore characteristics zeolites (HZSM‐5, HY‐zeolite, and MCM‐41).

Toward Understanding of Bio-Oil Aging: Accelerated Aging of Bio-Oil Fractions
ACS Sustainable Chemistry & Engineering, 2014Pyrolysis bio-oil from biomass is a promising intermediate for producing transportation fuels and platform chemicals. However, its instability, often called aging, has been identified as a critical hurdle that prevents bio-oil from being commercialized.
