摘要： 研究了以锯木屑、纸张、塑料的热解物(分别简称木炭、纸炭、塑料热解物)为原料制备中孔活性炭时孔结构发展的影响因素. 结果表明：当塑料热解物含量一定时，木炭、纸炭组成比的改变主要对活性炭的微孔产生影响，即二者的组成比越高，活性炭的微孔孔容越大；塑料热解物含量是活性炭中孔形成的主要影响因素，随着塑料热解物含量的增加，活性炭的中孔孔容先增加再减少；低的热解温度有利于活性炭中孔结构的形成和发展；最后对中孔形成的机理进行了探讨.

Abstract: In gaseous products of biomass steam gasification, there exist a lot of CO, CH4 and other hydrocarbons that can be converted to hydrogen through steam reforming reactions. There exists potential hydrogen production from the raw gas of biomass steam gasification. In the present work, the characteristics of hydrogen production from biomass steam gasification were investigated in a small-scale fluidized bed. In these experiments, the gasifying agent (air) was supplied into the reactor from the bottom of the reactor and the steam was added into the reactor above biomass feeding location. The effects of reaction temperature, steam to biomass ratio, equivalence ratio (ER) and biomass particle size on hydrogen yield and hydrogen yield potential were investigated. The experimental results showed that higher reactor temperature, proper ER, proper steam to biomass ratio and smaller biomass particle size will contribute to more hydrogen and potential hydrogen yield.
