| 摘 要： | 以离子液体1-丁基-3-甲基咪唑氯(Bmim]Cl)和1-丁基-3甲基咪唑四氟化硼(Bmim]BF4)为催化剂,在微波加热作用下,研究了稻草和锯屑的热解。微波加热20 min,稻草和锯屑的生物油产率分别为38%和34%。考察了微波加热时间、微波功率和离子液体用量对生物质油产率的影响。当以相同的离子液体为催化剂时,稻草微波热解得到的生物质油产率大于锯屑的。生物油成分主要有糠醛、醋酸和1-羟基-2-丁酮等,其含量主要取决于生物质原料和加入的离子液体的类型。

| Abstract: | The pyrolysis of rice straw and sawdust under microwave irradiation was performed with ionic liquids (ILs) 1-butyl-3-methylimidazolium chloride and 1-butyl-3-methylimidazolium tetrafluoroborate as catalysts. With microwave heating for 20min, the bio-oil yield from rice straw reached 38% and that from sawdust reached 34%. The effects of microwave heating time, microwave power, and IL dosage on bio-oil yields were discussed. The chemical components in bio-oil were analyzed by gas chromatography-mass spectroscopy technique. The main components in bio-oil are furfural, acetic acid, and 1-hydroxy-2-butanone, and their contents mainly depend on the source of biomass and the type of IL used in pyrolysis. |
