Abstract
Hydrothermal pretreatment was applied to wood sawdust, Trakya lignite
and wood sawdust-Trakya lignite mixture (50%, wt) individually. Changes
in fuel properties and thermochemical conversion characteristics of each
were observed. In addition, the synergistic effect of biomass on coal
with hydrothermal pretreatment of the mixture was investigated. After
hydrothermal pretreatment, where the optimum conditions were 230 °C and
90 minutes and under autogeneous pressure, fixed carbon percentage and
heating value increased and ash content decreased in all fuels. Compared
to lignite and wood sawdust, a fuel with higher elemental carbon
content, lower oxygen percentage and higher calorific value was... (More)

to lignite and wood sawdust, a fuel with higher elemental carbon
content, lower oxygen percentage and higher calorific value was obtained
when the mixture was co-hydrothermally pretreated. Hydrothermal
pretreatment applied to the mixture modified the structural properties
and volatiles of the mixture. For this reason, the reactivity of the
hydrothermal pretreated mixture in pyrolysis and combustion reactions
increased, and the peak temperatures at which the mass loss rate was
maximum were shifted to higher. (Less)
