Titre portugais : Caracterização de residos de biomassa vegetal para utilização energética

Quartile : Q4, Sujet : FORESTRY

Abstract : The use of plant residues for energy purposes is already a reality, yet in order to ensure suitability and recommend a given material as being a good energy generator, it is necessary to characterize the material through chemical analysis and determine its calorifi c value. This research aimed to analyze different residues from plant biomass, characterizing them as potential sources for energy production. For the accomplishment of this study, the following residues were used: wood processing residue (sawdust and planer shavings); coffee bean parchment and coffee plant stem; bean stem and pod; soybean stem and pod; rice husk; corn leaf, stem, straw and cob; and sugar cane straw and bagasse. For residue characterization the following analyses were done: chemical analysis, immediate chemical analysis, calorifi c value and elemental analysis. All procedures were conducted at the Laboratory of Forest Biomass Energy of the Federal University of Lavras. In general, all residues showed potential for energetic use. Rice husk was found to have higher lignin content, which is an interesting attribute as far as energy production is concerned. Its high ash content, however, led to a reduction in calorifi c value and fi xed carbon. The remaining residues were found to have similar energetic characteristics, with corn cob showing greater calorifi c value, followed by coffee plant stem, both also containing higher levels of carbon and fi xed carbon. A high correlation was found of higher calorifi c value with volatile materials, carbon and hydrogen contents. (Résumé d'auteur)
