| 摘 要： | 通过与常规热风干燥方式比较，研究生物质微波干燥过程及其对热解的影响，以探索在生物质快速热解液化工艺中采用微波干燥技术进行原料预处理的可行性。干燥实验表明，微波炉的干燥速率明显大于烘箱（5倍以上），同时在微波快速干燥过程中，原料内部的孔隙结构得到了改善。热天平上干燥样品的热解表明，微波干燥处理有利于生物质的热解，特别是纤维素和半纤维素的热解，并且能在一定程度上抑制生物油蒸汽的二次裂解反应，从而使实际流化床热解液化装置中的生物油产率有所提高。研究表明，将微波干燥技术用于生物质热解液化的原料预处理过程在技术上和经济上均具有可行性。

| Abstract: | The influence of microwave drying on the pyrolysis of biomass was investigated compared with conventional air drying.The aim of this work is to seek the feasibility of using microwave drying technique in fast pyrolysis of biomass during pretreatment of the feedstock.The drying tests show that the drying rate of microwave oven is far faster than that of electrical oven.The inner pore characteristics of dried biomass are improved at higher drying rate.The thermogravimetric and kinetic analysis indicate that t... |
