摘要
以中国农业大学5个学生食堂厨余垃圾按照日产量比例混配后作为原料(含固量,22.54%),研究反应温度(260、290和320℃)对水热液化反应和产物分布的影响。最大液化率和最大产油率分别为79.25%(290℃)和42.02%(260℃),生物原油热值最高可达37.39 MJ/kg,能量回收率最高可达65.96%。GC-MS分析表明生物原油由烃类、酸类、醇类、酮类和醛类等物质组成。
The kitchen waste from five canteens in China Agricultural University (CAU)were mixed to be the feedstock (TS, 22.54% ) for HTL after blending without dilution. The influence of holding temperature (260 ℃, 290 ℃, 320 ℃ ) on HTL of kitchen waste was then performed with a retention time of 0.5 h and initial pressure of 1.1 MPa. The highest oil yield and highest energy recovery was obtained as 42.02% and 65.96% at 260 ℃, whereas the liquefaction rate and oil higher heat value (HHV)achieved their maximum at 290 ℃ as 79.25% and 37.39 MJ/kg, respectively. The analysis of GC-MS revealed that the main components of bio-crude oil are hydrocarbons, acids, alcohols, ketones and aldehydes.
