This study found that the residue content of oil-bath co-torrefaction was the highest at 97.01%. Oil-bath co-torrefaction can maximize the retention of hydrogen atoms in corncob, which is beneficial for deoxygenation during pyrolysis. It can also reduce the average activation energy required for corncob decomposition.
Lignocellulosic biomass is a rich source of fixed renewable carbon and a promising alternative to fossil sources. However, low effective hydrogen to carbon ratio limits its applications. This work studied the influence of oilbath co-torrefaction of corncob and waste cooking oil for co-pyrolysis. It was compared with dry torrefaction and hydrothermal wet torrefaction firstly. Residual of oil-bath co-torrefaction were the highest of 97.01 %. Oilbath co-torrefaction could maximize hydrogen atoms retention in corncob, which has a positive significance for deoxygenation during pyrolysis. Oil-bath co-torrefaction could also reduce the average activation energy required for corncob decomposition, while it was increased with dry torrefaction. Oil-bath co-torrefaction coupled with co-pyrolysis was more suitable for hydrocarbon-rich bio-oil production. Oil-bath co-torrefaction temperature had the greatest influence on bio-oil composition. High pressure promoted formation of the C--C double bond and degradation of lignin, which further promoted the formation of monocyclic aromatics in bio-oil.
