玉米秸秆在乙醇/水混合溶剂中液化制生物油的研究
Liquefaction of Corn Stover in Ethanol/Water Co-solvent for Bio-oil Production
摘要
Abstract
The effect of temperature(180 -340℃)on the ethanol steam reforming(ESR)with NiMoS/Al2O3as catalyst was investigated in batch-type autoclave.The behavior of corn stover liquefaction in the ethanol-water co-solvent was studied.Results showed that the ESR occurred as the temperature increased to 320℃with NiMoS/Al2O3,accompanied with the formation of CO, CO2,CH4,H2and CnHm,of which the H2yield was the highest(47 mmol).When the temperature was further increased to 340℃,the H2yield remarkably increased to 122 mmol.Compared to the non-catalytic runs,the yield and heating value(QHHV) of bio-oil obtained from corn stover liquefaction at 340℃with NiMoS/Al2O3as catalyst increased from 21.26%and 32.14 MJ/kg to 29.57%and 33.89 MJ/kg,respectively.GC-MS results showed that the main components of the bio-oil were phenolics,esters and ketones,and the phenolics content decreased by 23%after adding the catalyst,which was beneficial to increase the stability of bio-oil.关键词
