ABSTRACT = {A new method of pretreatment of corn straw with <i>Phanerochaete chrysosporium</i> combined with pyrolysis was
proposed to improve the quality of bio-oil. The characterization results demonstrated that microbial pretreatment
was an effective method to decrease the lignin, which can achieve a maximum removal rate of 44.19%. Due to the
destruction of biomass structure, the content of alkali metal and alkaline earth metal is reduced. Meanwhile, the
depolymerized biomass structure created better pyrolysis conditions to promote the pyrolysis efficiency, increase
the average decomposition rate of pyrolysis and reduce the residue. In fast pyrolysis, because of the enrichment of
cellulose and the removal of lignin, the contents of acids, linear carbonyls, furans, and sugars increased while the
contents of phenols decreased. As for the catalytic pyrolysis, due to the hydrocarbon pool reaction and shape
selection deoxidation of ZSM-5 catalyst, the total hydrocarbon and aromatics contents can significantly increase
up to 34.37% and 30.59%, respectively, with 3 weeks of pretreatment. And the the low molecular content of bio-oil
increased after pretreatment, which can significantly benefit the entry of primary pyrolysis steam into the catalyst
pores to improve the catalytic efficiency and hydrocarbon contents. This method provides a new treatment idea
for high-quality utilization of biomass.},
