Biomass resources are abundant renewable resources, its research and development will greatly im-prove its biomass energy value. Pyrolysis technology is one of the most effective ways of conversion of biomass en-ergy. Biomass can be changed into high quality clean energy or high value chemicals through pyrolysis, which at-tracts more and more attention. In this paper, the overview of biomass pyrolysis was described, the impacts of the pyrolysis temperature, heating rate, pressure, material characteristics（biomass species, particle size, molecular structure, etc.） on biomass pyrolysis process and product distribution characteristics were summarized. The tech-nologies for separating and analyzing bio-oil were introduced. The research status, application field and the major problems existing in the process of using were reviewed.
