A Study on The Thermal Properties and Activation Energy of Rapidly Torrefied Oak Wood Powder using Non-isothermal Thermogravimetric Analysis Lee, Danbee; Kim, Birm-June;
This study investigated thermal properties and activation energy () of torrefied oak wood powders treated with various torrefaction times (0, 5, 7.5, 10 min) by using non-isothermal thermogravimetric analysis at heating rates of 10, 20, to check the feasibility of rapidly torrefied oak wood powders as a fuel. As the torrefaction time increases, onset of thermal decomposition temperature, lignin content, and the amount of final residue of torrefied oak wood powders were accordingly increased with reduced hemicellulose content. was determined by using Friedman and Kissinger models and respective R-square values were over 0.9 meaning very good availability of calculated values. The values of the samples were decreased with the increase of torrefaction time and the lowest value ob served in the torrefied oak wood powders treated for 7.5 min showed high feasibility of rapidly torrefied oak wood powder as a biomass-solid refuse fuel.
