Abstract: The thermogravimetric analysis of the furfural residues was done at the atmosphere of
N2 at first in this paper. Then the suitable carbonization conditions were fixed by the weightless
curve. Namely carbonization temperature was 450℃and the carbonization time was 1h. The
composition and the content of the pyrolysis gases were analyzed at different temperatures. The
content of H2, CO, CH4 were all increased with the temperature increasing. Subsequently, the
effect of activation temperature, activation time and the water flux to the performance of activated
carbon were investigated. So the activation conditions were determined as follows, the activation
temperature was 850℃, the activation
