Biochar production and mixing in soil are seen as the best options for atmospheric carbon sequestration,not only providing simultaneous benefits to soil,but also opportunities for distributed energy generation.A number of methods can be used for producing biochar,and production of bio-oil,gas and biochar from pyrolysis of biomass is considered a promising technology for combined production of bioenergy and carbon sequestration. Thermogravimetric analysis of the biochar was made on a high pressure high temperature ThermoGravimetric Analyzer,The complete setup is manufactured using corrosion resistant materials,and the application of a magnetic suspension balance enables experiments to be carried out in a large temperature and pressure *** the sensitivity of the balance is checked and calibrated during the experiments automatically because of the fully automatic,regularly checking of a reference measuring point which eliminates any drift of the baseline of the instrument. The pyrolysis reactivity and structure of biochar produced from wood powder,corncob,wheat straw and the effects of pyrolysis temperature were *** samples were prepared by ThermoGravimetric Analyzer in N under heating rate 10℃/min～50℃/minto a final temperature of 650℃～850℃.The results indicate that the final pyrolysis temperature and rate influenced the outputs of biochar,as well as the stability of the biochar *** is found that char increases with the decreasing of pyrolysis temperature and with the increasing of heating rate,Contrary to slow heating rate a faster heating rate may result in incomplete conversion of biomass due to limitations to heat transfer and *** was shown that the weight loss of different biomass at the same final pyrolysis temperature was different due to the content of cellulosic and hemicellulosic fractions in *** woody biomass（wood powder） and herbaceous biomass（corncob） also have different *** biomass loose
