P-16 Influence of Sample Size on Semi-Carbonization Behavior of Biomass Packed Bed

Abstract

In this study, we measured the packed bed temperature and gas generation amount at the time of torrefaction using bamboo powder and bamboo blocks, in order to investigate the influence of the sample on the torrefaction. As a result, as the sample size increased, the packed bed temperature reached the maximum temperature earlier and the maximum value of the gas generation amount became larger. This may be because heat generated by pyrolysis of xylan was not released due to heat storage effect of bamboo and thermal decomposition was promoted. However, since the heat storage effect depends on the smallest side, there is a limit to the improvement of the heat storage effect by enlarging the sample size
