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.

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

2010 International Conference on Optoelectronics and Image Processing, 2010
Pyrolysis oil (also called bio-oils) produced from biomass is a promising substitute for fossil fuels. However, bio-oil has many shortcomings, such as high viscosity, high oxygenate content, low stability and low heating value. Therefore, it is hard for direct high-grade fuel utilization before upgrading.

Steam Gasification of Bio-Oil and Bio-Oil/Char Slurry in a Fluidized Bed Reactor
Energy & Fuels, 2010Bio-oil/char mixtures and whole bio-oil from rapid pyrolysis of woody biomass are potential feeds for synthesis gas production via steam gasification. A 7.8 cm diameter, atmospheric pressure, fluid bed gasifier was constructed and operated with either a nickel-containing steam reforming catalyst or silica sand as bed material. Both bio-oil and a slurry

Electrochemical Upgrading of Bio-Oil
ECS Meeting Abstracts, 2016Alternative fuels derived from biomass “biofuels” are an attractive alternative to substitute limited and non-renewable sources of energy. Bio-oil generated from the pyrolysis of biomass is a complex micro-emulsion with high levels of oxygen and acids, which lead to increases in viscosity, phase separation, and degradation as it ages.

Bio-oil valorization: A review
Renewable and Sustainable Energy Reviews, 2013Abstract Fuels from biomass (biofuels) are used to mitigate the greenhouse gases produced through the utilization of fossil fuels. Non-edible or waste biomass can be pyrolyzed to produce bio-oil. The oil, an unstable and low energy product, can be further upgraded through hydrodeoxygenation to produce gas and/or diesel range hydrocarbons and value ...

Multiphase Structure of Bio-oils
Energy & Fuels, 2005The multiphase complex structure of biomass pyrolysis oils can be attributed to the presence of char particles, waxy materials, aqueous droplets, droplets of different nature, and micelles formed of heavy compounds in a matrix of hollocellulose-derived compounds and water.

Electrochemical Upgrading of Bio-Oil
ECS Transactions, 2017Bio-oil produced by fast pyrolysis of biomass is a potential source of low carbon, renewable hydrocarbon fuel. However, the properties such as low heating value, incomplete volatility, acidity, instability, and incompatibility with standard petroleum fuels significantly restrict its use as fuel. The undesirable properties of pyrolysis oil result from

Hydrotreating for Bio-Oil Upgrading
2010Bio-oils are produced from various biomass sources through processes such as pyrolysis and hydrothermal treatment. While conventional oils from fossil energy sources contain less than 0.1 wt% oxygen, the oxygen content of bio-oils can reach as high as 50 wt% causing several undesired properties such as high viscosity, instability and low energy content.
