摘要
考察不同热化学处理方式对稻壳炭的得率、工业分析及比表面积、总孔容积、孔径分布的影响,结果表明:固定床热解气化的稻壳炭得率最高,为33.01%,且工业分析中固定碳的含量最高,为49.25%,比表面积最大,为222.210 m^2·g^(-1),平均孔径最小,孔径分布以微孔为主;热解炭化的稻壳炭总孔容积最大,为0.204 cm^3·g^(-1),平均孔径最大。
The effects of different thermochemical treatments on the yield, industrial analysis, specific surface area, total pore volume and pore size distribution of rice husk char were researched in this paper. Results showed that the rice husk char yield was highest by the fixed bed pyrolysis gasification which was 33.01%. The content of fixed carbon in the industrial analysis was highest which was 49.25 %, and the specific surface area was the largest which was 222.210 m2.g-1. The average pore size was minimum and pore size distribution was mainly microporous. The total pore volume of rice husk char was the largest at 0.204 cm3.g-1 which was produced by pyrolysis carbonization, and the average pore size was the largest.
