Abstract:
Biomass torrefaction is a thermochemical
pretreatment process at a temperature range of 200-3000C
in an inert environment. Moisture and hemicellulose are
released during the process resulting in an energy
densified solid fuel. In this research, rubberwood is used
to make torrefied wood inside a batch reactor.
Temperature and the residence time are the two operating
variables optimized. 250, 275 and 300 are considered as
the experimentation temperatures kept at residence times
of 30, 45 and 60min. A mass loss of 12% for rubberwood
was observed. It can be observed that the higher heating
value (HHV) increases with the increase of torrefaction
conditions. From the experimentation results it can be
concluded that the torrefaction conditions of 3000C, 60min
gives the optimum results.
