Abstract


The Higher Heating Value (HHV) of rice husks, peach stones andeucalyptus sawdust was determined, as well as of the resulting bio-oils andresidual chars from low temperature conversion process. Products yields forbio oils varied from 16 to 26%, and for solid residue, from 38 to 48%. HHV of3,900, 2,600 and 4,100 cal/g were measured for rice husks biomass, its residualchar and bio-oil; 4,100, 5,800 and 4,000 cal/g, for eucalyptus sawdust, its charand bio oil; 3.,400, 3,200 e 3,900 cal/g, for peach stones, its char and bio oil,respectively. These values show that biomasses and pyrolysis products canbe considered as renewable energy sources, clean and neutral to global warming.
