使用自制的微波热重分析装置,对压缩打包后的小麦和玉米秸秆进行了微波热解试验,考察了微波辐射下秸秆的热解特性和影响因素.使用气相色谱对气体产物进行了定性定量分析,考察了气体的热值,并与常规热解得到的气体产物进行了比较.结果表明:秸秆的微波热解过程可以划分为干燥、预热解、挥发份大量析出和炭化等4个阶段,物料种类和微波功率对热解过程具有重要影响.热解气体产物中主要成分为氢气、一氧化碳、二氧化碳、甲烷等.较高的氢气含量预示着秸秆微波热解可以用来生产富氢燃气,研究结果为生物质微波热解的工业应用提供了基础性数据.

The initial work into the pyrolysis of straw bale using microwave energy was described. A series of batch exper-iments were carried out using a microwave thermogravimetric apparatus at different conditions, such various straw and mi-crowave power level. Component analysis of gaseous products was carried out using gas chromatography which provides a comparison with gaseous product produced using conventional methods. The results shown that the microwave pyrolysis process is composed of four stages: drying, pre-pyrolysis, volatile releasing massively and carbonization, and material type and microwave power have important impacts on it. The major compositions in gaseous products are H_2, CO_2, CO, CH_4. The high H_2 content imply that microwave pyrolysis of biomass has the potential to produce the H_2-rich fuel gas. The research results provide the fotmdational data for the industrial utilization of biomass using microwave technology.
