Preliminary Study Of Dairy Manure Torrefaction For Biochar Production
Torrefaction is a thermochemical treatment techniques performed at low temperature in an inert atmosphere to
transform a biomass into a value-added bioenergy. In this study, fresh dairy manure was torrefied using a rotary kiln
combustion type reactor at 200oC, 250oC and 300oC and the manurewas treated up to four timesfrom each temperature. The
findings showed that the mass yield of the torrefied dairy manuredecreased gradually with the treatment times due to
dehydration. Biochar at 250oC was preferable in consideration of final mass yield and duration time taken for the production.
