摘　　要：选取棉秆在微波反应器中进行不同干燥温度和初始含水率下的干燥实验,发现微波干燥可迅速降低生物质原料的含水量,同时实现深度干燥;微波干燥可有效增大原料的比表面积,丰富生物质的孔隙结构。The cotton stalk drying experiments under different drying were carried out using a microwave reactor. The results indicate temperatures and different initial moisture contents that under microwave drying condition, the moisture contents of cotton stalk decrease rapidly and achieve deep dry as well. Meanwhile the specific surface area of cotton stalk can be significantly increased and the pore structure becomes more abundant.

关 键 词：生物质 微波干燥 深度干燥 孔隙结构
