Resumo

A utilização de biomassas residuais de plantas utilizadas na agroindústria tem sido crescente. O bagaço de cana-de-açúcar se destaca nesse cenário, já que a cultura da planta é muito difundida, gerando grandes quantidades desse resíduo. Neste contexto é necessário entender as características dessa biomassa para poder otimizar a geração de energia. Diante do exposto, o presente trabalho teve como objetivo caracterizar e avaliar o potencial energético da biomassa de cana-de-açúcar por meio da análise dos principais parâmetros que influenciam esse processo. Foram realizadas análises de poder calorífico superior, análises químicas imediatas, infravermelho e análise elementar, com o intuito de avaliar o potencial energético desse material. Observou-se bom nível de poder calorífico superior, 4309,50 kcal kg-1, além de teores baixos de cinzas, 0,95%, fatores que podem explicar a grande utilização da biomassa de bagaço de cana-de-açúcar para a geração de energia direta, principalmente na indústria.

Characterization of sugar cane bagasse biomass with energy views

Abstract

The use of residual biomass from plants used in agribusiness has been increasing. The sugarcane bagasse stands out in this scenario, since the plant's culture is very widespread, generating large amounts of this residue. In this context, it is necessary to understand the characteristics of this biomass in order to optimize the energy generation. With the above, the present study had as objective characterize and evaluate energy potential of sugarcane biomass through the analysis of the main parameters that influence the process. Analyzes of superior calorific power, immediate chemical analyzes, infrared and elementary analysis were carried out, in order to evaluate the energetic potential of this material. A good level of higher calorific value was observed, 4309.50 kcal kg-1, in addition to low ash content, 0.95%, factors that may explain the great use of sugarcane bagasse for direct energy generation, mainly in industry.

Keywords: Waste. Sugarcane. Energy source.
