摘　　要：稻壳热解可以进一步缓解资源浪费和环境污染问题。经过不同预处理的稻壳会产生不同的热解效果。研究采用真空、热风和微波三种干燥方式对稻壳进行预处理,收集并分析稻壳热解过程中的失重情况和三相产物的产率,通过FWO法拟合计算活化能。采用SEM、XRD等方法对热解产物进行表征和分析。结果表明:微波处理后的稻壳表面孔隙增多,在相同升温速率下微波处理稻壳热解失重率最大,平均活化能最高,热风处理后固体产物产率最大。Rice husk pyrolysis can further alleviate issues of resource wastage and environmental pollution.Different pre-treatments of rice husk lead to varying pyrolysis outcomes.In this study,rice husk was pre-treated using vacuum,hot air,and microwave drying methods,with the aim of collecting and analyzing weight loss during pyrolysis and the yield of three-phase products,while calculating the activation energy through the Flynn-Wall-Ozawa method.Characterization and analysis of pyrolysis products were conducted using SEM,GC-MS,and XRD techniques.The results indicated that microwave-treated rice husk exhibited increased surface porosity,the highest weight loss rate during pyrolysis at the same heating rate,the highest average activation energy,while the highest solid product yield was observed after hot air treatment.
