Bioresource Technology, 2010
In this study, cattle manure was converted to bio-oil by subcritical hydrothermal liquefaction in the presence of NaOH. The effects of conversion temperature, process gas, initial conversion pressure, residence time and mass ratio of cattle manure to water on the bio-oil yield were studied.

Progress of the applications of bio-oil
Renewable and Sustainable Energy Reviews, 2020Abstract Bio-oil is considered a renewable feedstock for the production of energy, fuels, chemicals and carbon materials. These specifically include the direct combustion of bio-oil as a boiler fuel, the production of biofuel from bio-oil via hydrotreatment, or the production of value-added chemicals via separation and acid-catalysis/hydrogenation or

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.

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).

Catalytic Upgrading of Bio‐Oils by Ketonization
ChemSusChem, 2009Esterrific and ketonderful! Mixtures of acids and esters, produced by esterification reactions with alcohols in bio-oils, can be upgraded to larger ketones by ketonization reactions using a ceria–zirconia catalyst, on which acids adsorb more strongly than esters, leading to the preferential ketonization of acids followed by ketonization of esters at ...

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

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.
