Abstract: The characteristic feature of flash pyrolysis and conventional pyrolysis of bamboo were investigated. The operating conditions of flash pyrolysis was: temperature 500℃, residence time of volatile matter 0.76 s and heating rate 28℃/s. The yield of the liquid product was 48.5%, containing 2,6-dimethoxy phenol and 2-methoxy phenol as major constituents.The processing condition of conventional bamboo pyrolysis was: heating rate 1℃/min and temperature 500℃. The yield of liquid products including water was 30%, containing acetic acid as major constituent. In conventinal pyrolysis at temperature less than 550℃, the main pore diameters were 6.0-22.0 nm. At pyrolysis temperature 650-750℃, the main pore diameters were less than 2 nm.

Key words: pyrolysis, micropore, phenols, bamboo
