【Abstract】 Walnut shells were carbonized at 300～700℃. 25%～30% (wt)charcoal, 6% ～15% (wt) tar and 25% ～35% (wt) gas were obtained. The effects of carbonization temperature on product ratio, specific surface area of the charcoal,air separation ability of the charcoal and the composition of the gas were discussed. The result shows that the 500～700℃ charcoal is suitable carbon precursor of activated carbon or carbon molecular sieves,and the gas could be used as city gas.更多还原
