摘要：对6种木质活性炭自燃性质的影响因素进行了研究。研究表明活性炭的临界自燃温度与其制造工艺和设备有关。挥发分(碳氢氧化合物)、氧含量、氢含量和表面含氧官能团及粒度是影响活性炭临界自燃温度的主要因素。磷酸法活性炭临界自燃温度最低(180℃),水蒸气法活性炭由于经过1 000℃活化过程,在试验范围内无自燃性质。另外,平板炉制造的粉状活性炭比回转炉制造的粉状活性炭的临界自燃温度高。
The influence factors on the self-ignition properties of six kinds of woody powdered activated carbon were studied. The critical self-ignition temperature （CIT） of activated carbon is related to manufacture processes and equipments. Studies have shown that volatile, oxygen, hydrogen and surface oxygen-containing functional groups are main factors that affect the CIT of activated carbon. Activated carbon manufactured by phosphoric acid has the lowest CIT （ 180 ℃ ）, but the activated carbon manufactured by steam has the highest CIT since its activation temperature is high as 1 000 ℃ and it has no self-ignition property. In addition, powdered activated carbon manufactured by flat furnace has higher CIT than that manufactured by rotary furnace.
