This paper presents an investigation of hydrothermal liquefaction of waste meat for liquid fuel. Pork from diseased dead pigs was used as feed stock for liquid fuel production. The effects of process parameters (temperature and pressure) on the yields of liquid fuel and solid residue were determined. Heat value

elemental analysis and chemical composition of the liquid fuel were determined and analyzed. The obtained liquid fuel had calorific value of 39.31 MJ·kg-1

viscosity(20℃) of 20.5 mPa·s

flash point of 70℃ and cold filter plugging point of 8℃ under operating conditions (250℃

4.0 MPa). The liquid fuel was a complicated mixture mainly consisting of aromatic hydrocarbon

ketones

ethers

esters

furan

and a few acids. The liquid fuel could be used as fuel in boiler or furnace for heat generation

and might be a potential resource of automotive fuel after refining.
