摘要
The thermal analysis and kinetics of bio-oils derived from swine manure/crude glycerol co-liquefaction were studied by thermogravimetric analysis (TGA) in the air. It was found that the combustion processes of bio-oils can be divided into three stages, with most of the materials decomposing between 330 and 370 degrees C. In kinetic calculations, oxidation of the bio-oils was determined using the Coats-Redfern method, considering that bio-oil combustion occurs in three consecutive steps. Four models including more than 12 alpha functions were tested to fit the study's experimental results. The calculation shows that the diffusion models are the best fit for describing the bio-oil combustion process in the air.
