利用EXCEL分析焦样的孔径分布

Discussion of Pore-size Distribution of Biomass Chars Making Use of Excel

Excel是目前最常用的办公软件之一,本文利用excel画出生物质焦样的孔径分布图。本文选取稻壳、树叶、玉米秆、棉花秆四种生物质制成生物质焦,并采用压汞法测量焦样的孔径分布。实验结果表明,不同生物质制成的焦样的孔径分布曲线差别很大,同一生物质不同热解条件焦样的孔径分布曲线很相似。这表明热解条件对生物质焦孔径分布有影响但影响不大,决定生物质焦孔径分布的是生物质种类本身。

Excel is one of the most favorite office software.In this paper,Excel is used to generate biomass chars’pore-size distribution diagrams.Four kinds of biomasses of rice hull,leaf,cornstalk and cotton stalk are made into biomass chars,and the pore-size distribution of biomass chars are measured by mercury intrusion method.The results show that pore-size distribution curves of different kinds of biomass are quite different.And the pore-size distribution curves of same kind of biomass with different pyrolysis conditions are similar.It shows that the influence of pyrolysis conditions on pore-size distribution is small.The kinds of biomass decide the pore-size distribution curves.
