The Character Research Of Bio-oil And Biomass Material

This research is a part of project subsidized by science and technology department of Jilin Province named as " The technology of pyrolysising biomass for bio-oil" (serial number: 20000320).On the basis of completing successfully the experiment which is biomass pyrolysis for producting bio-oil with a fluidized bed reactor and the reactor is the most biggest by Chinese exploiting, this text is coming.This paper concludes detailed the current status of biomass pyrolysis for liquid product in china and overseas, especially about analysis of bio-oil composition. From the point of view of continuable development, the technology of biomass pyrolysis for producting bio-oil has a good prospect.Physical characters of biomass materiel which include dentsity, caesural angle and granule distribution were analyzed.These characters of biomass materiel are very important for designing fluidized bed and all system, and they are important affecting factor for the pyrolysis process too. We use Van Soest abstersion fibre to determine different biomass component.Physiccal properties of bio-oil from the experiment of biomass pyrolysis were analyzed with precising apparatus nowdays and compared on some relevancing aspect,these physical properties include mainly density, acidity, viscosity and caloric value. In analyzing bio-oil component, an advanced means which is GC-MS analysis was used. Bio-oil component were compared in defferent experiment parameter The influence of process parameters for bio-oil properties were contrasted.According to component analysis, explain high oxygen content and high water content. In order to offer credible data for experiment parameter, so we can make certain what is bio-oil with good quality and high producting rate by component analyzed.In order to optimize quatity and quality of boi-oil, the theory of biomass component pyrolysis were discussed with combining research status of overseas and China.In conclusion, these foundation researches of biomass flash pyrolysis for producting liquid fuel is significant for optimizing experiment parameter, forecasting the result of experiment and magnifying equipment etc.
