![عکس صفحه اول مقاله: Effect of sodium perborate monohydrate concentrations on product distributions from the hydrothermal liquefaction of Scotch pine wood Effect of sodium perborate monohydrate concentrations on product distributions from the hydrothermal liquefaction of Scotch pine wood](/preview/png/209975.png)
The hydrothermal liquefaction of biomass was carried out using sodium perborate monohydrate (NaBO3⋅H2O) at 250, 300 and 350 °C. The effects of temperature and additive concentrations on the product distributions were investigated. NaBO3⋅H2O was found to be very effective for the hydrothermal liquefaction of biomass at 300 and 350 °C. The use of NaBO3⋅H2O in the liquefaction of woody biomass increased the yields of bio-oils and decreased the solid residue yields at 300 and 350 °C. All concentrations of NaBO3⋅H2O showed high catalytic performance at 300 and 350 °C. The identified compounds in bio-oils (light bio-oils and heavy bio-oils) were mostly oxygenated hydrocarbons for both the thermal and NaBO3⋅H2O runs. Furfural, 5-methyl furfural, and 5-(hydroxymethyl)furfural were only observed in the thermal run. Most of the identified compounds in the light bio-oils obtained from the thermal and NaBO3⋅H2O runs were phenolic compounds. The highest heating value of the resultant heavy bio-oils was approximately 32 MJ/kg, which was obtained from the hydrothermal liquefaction of biomass at 350 °C with NaBO3⋅H2O.

► Woody biomass was converted into bio-oil via hydrothermal processing in the absence and presence of NaBO3⋅H2O.
► The effects of both temperature and additive concentration were investigated.
► The optimal experimental conditions for obtaining the maximum bio-oil yield were 300 °C by using 10 wt% of NaBO3⋅H2O.
