CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Optimal condition for torrefaction of eucalyptus by response surface methodology

Exporter la citation

The optimal condition for the torrefaction of eucalyptus (Eucalyptus globulus) was investigated by response surface methodology. The carbon content in the torrefied biomass increased with the severity factor (SF), while hydrogen and oxygen contents decreased. The calorific value of torrefied biomass ranged from 20.23 to 21.29 MJ/kg, depending on the torrefaction conditions. This implied that the energy contained in the torrefied biomass increased by 1.6 to 6.9%, when compared with that of the untreated biomass. The weight loss of biomass increased as the SF increased. The Code level of reaction temperature had the highest impact on the energy yield of torrefied biomass, while the effect of Code level of reaction time was considerably low. The highest energy yield was obtained at low SF.
