Bamboo was a popular material substituting for wood,especially for one-off commodity in China. In order to recover energy and materials from waste bamboo,the basic characteristics of bamboo pyrolysis were studied by a thermogravimetric analyzer. It implied that the reaction began at 190~210 °C,and the percentage of solid product deceased from about 25% to 17% when temperature ranged from 400 °C to 700 °C. A lab-scale fluidized-bed furnace was setup to research the detailed properties of gaseous,liquid and solid products respectively. When temperature increased from 400 °C to 700 °C,the mass percent of solid product decreased from 27% to 17% approximately,while that of syngas rose up from 19% to 35%. When temperature was about 500°C,the percentage of tar reached the top,about 31%. The mass balance of these experiments was about 93%~95%. It indicated that three reactions involved in the process: pyrolysis of exterior bamboo,pyrolysis of interior bamboo and secondary pyrolysis of heavy tar.
