摘要/Abstract

摘要： 开展了肉质废物水热液化制备液体燃料的研究。选用病死猪肉为水热液化实验代表材料，考察了得到的液体燃料和残余固体产率随温度和压力的变化规律，测定了液体燃料的热值、黏度、闪点和冷滤点等燃料性质以及液体燃料的元素成分，分析了液体燃料的部分化学成分。在温度为250℃，压力为4.0 MPa条件下水热液化获得的液体燃料的热值为39.31 MJ·kg^-1，黏度（20℃）为20.5 mPa·s，闪点为70℃，冷滤点为8℃，其化学成分较复杂，包含较多的芳香烃，还含有酮类、酯类、醚类、羧酸和呋喃等各种化合物。研究结果表明，该液体燃料可用于锅炉、工业窑炉的燃烧供热，进一步精炼后有望用于机动车辆。

Abstract: 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, viscosity, flash point, cold filter plugging point, 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.
