细叶桉亚临界水热液化中固体残渣分析

Analysis of Solid Residue in Subcritical Liquefaction of Eucalyptus Tereticornis Smith

以细叶桉为原料,对其进行不同温度(260、280、300和320℃)条件下,保温时间为30min的亚临界水热液化,并探讨温度对固体残渣的影响。实验结果表明,当温度为260℃时,固体残渣得率高达37.5%。固体残渣是带有多孔结构的无定形炭,其孔隙随着液化温度的升高而增多。

The subcritical hydrothermal liquefaction of Eucalyptus tereticornis Smith was carried out at260,280,300 and320℃ for30 min. The effect of temperature on the solid residue (SR) was investigated. Results showed that the SR had the highest yield at260°C (37.5%). In addition, the SR was an amorphous carbon which filled with porous structure, and the pore of SR was increased with increasing temperature.
