The torrefaction assays were carried out at temperatures of 240, 260, and 280 degrees C for 30 and 60 min to investigate the chlorine (Cl) behavior in Eucalyptus sp. from the region of Paraiba Valley, Brazil. The solid product obtained from the reactions - torrefied wood - was analyzed for mass loss, elemental analysis, calorific value, scanning electron microscopy, and chlorine content. The results showed that the mass loss ranged from 11.5 to 16.7% at the lowest temperatures tested, reaching 37.2% at 280 degrees C for 60 min. The samples torrefied at 260 and 280 degrees C for 60 min showed characteristics similar to lignite and peat, which have higher heating values. However, torrefied reactions of 30 min had better energy yields (97.6%). It is noteworthy that during torrefaction at 240 degrees C and 260 degrees C for 30 min, the chlorine reduction was 88 and 95% respectively, in relation to raw wood, resulting in concentrations of 30 and 13 mg kg(-1) of chlorine in the torrefied samples, meeting the specification of the ENplus standard (< 200 mg kg(-1)). Thus, torrefaction is a pretreatment process for Eucalyptus sp. from Paraiba Valley, state of Sao Paulo (Brazil), to produce biofuel with low chlorine content, enabling its commercialization in the European market.
