Abstract: During biomass fast pyrolysis process, the occurrence of free radical reactions generates a certain amount of free radical intermediates. Hydrogen free radicals from hydrogen donors will stabilize these intermediates to effectively regulate the distribution of char and high grade bio-oil to achieve value-added utilization of biomass. This paper summarizes the effects of hydrogen donors(1,2,3,4-tetrahydronaphthalene, linear alcohols, organic macromolecule polymer, etc.) on the fast pyrolysis of biomass, and the hydrogen free radicals supply mechanisms from different hydrogen donors. Afterwards, the commonness and the characteristics of biomass pyrolysis with the addition of different hydrogen donors are concluded. Finally, perspective researches are proposed to extend the selection of hydrogen donors and optimize the regulation of pyrolytic products.

Key words: hydrogen donor, hydrogen free radicals, biomass, fast pyrolysis
