Influence of biomass pretreatment on upgrading of bio-oil: Comparison of dry and hydrothermal torrefaction

[Display omitted] •Dry and hydrothermal torrefaction were compared via batch, quart tube, and auger.•Physical and chemical properties of torrefaction bio-char was investigated.•Batch autoclave and auger promoted the hemicellulose to strip from the CS.•Torrefaction is beneficial for the accumulation...
