Abstract

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.
