Abstract: The effects of pyrolysis temperature, residence time, particle size and heating rate on characters of pyrolysis gas of Eupatiorium adenophorum stem in fixed bed was investigated. The results showed that, H2 content, which was up to 70%, increased with the promotion of pyrolysis temperature, residence time, particle size as well as the decrease of heating rate. H2 content is much higher than that got from several already used biomasses; CO content increased with the promotion of temperature; CH4 content declined with the increase of temperature, residence time and heating rate. Heat value of gas was about 10000~13500 kJ/m3, which is middle heat value, decreased with the increase of temperature, residence time, particle size and the promotion of heating rate increased first then decreased.

Key words: Eupatorium adenophorum, pyrolysis temperature, residence time, particle size, heating rate
