Resumo: | http://dx.doi.org/10.5902/1980509812361The evaluation of lignocellulosic wastes for bioenergy production demands to consider several characteristicsand properties that may be correlated. This fact demands the use of various multivariate analysis techniquesthat allow the evaluation of relevant energetic factors. This work aimed to apply cluster analysis and principalcomponents analyses for the selection and evaluation of lignocellulosic wastes for bioenergy production.8 types of residual biomass were used, whose the elemental components (C, H, O, N, S) content, lignin, totalextractives and ashes contents, basic density and higher and lower heating values were determined. Bothmultivariate techniques applied for evaluation and selection of lignocellulosic wastes were efficient andsimilarities were observed between the biomass groups formed by them. Through the interpretation of thefirst principal component obtained, it was possible to create a global development index for the evaluationof the viability of energetic uses of biomass. The interpretation of the second principal component alloweda contrast between nitrogen and sulfur contents with oxygen content. |

Este fato demanda o emprego de diversas técnicas de análise multivariada que possibilitem a avaliação dos fatores energéticos mais relevantes. O objetivo deste trabalho foi aplicar as análises de agrupamento e componentes principais na seleção e avaliação de resíduos lignocelulósicos visando à produção de bioenergia. Foram utilizados 8 tipos de biomassa residual, dos quais foram determinados os teores dos componentes elementares (C, H, O, N, S), os teores de lignina, extrativos totais e cinzas, a densidade básica e o poder calorífico superior e inferior. As duas técnicas multivariadas empregadas para a avaliação e seleção de resíduos lignocelulósicos para a produção de energia foram eficientes, sendo observadas similaridades entre os grupos de biomassa formados por elas. Pela interpretação da primeira componente principal obtida, criou-se um índice de desempenho global para avaliar a viabilidade do aproveitamento energético da biomassa. A interpretação da segunda componente principal permitiu um contraste entre os teores de nitrogênio e enxofre e o teor de oxigênio.
