Análise de viabilidade técnica e projeção econômica da biomassa cama de aviário e seus produtos através da conversão energética pela pirólise

Abstract

The poultry sector in Brazil has great economic importance, being a world highlight in this category, all this production ends up generating large volumes of poultry litter biomass, which needs a correct destination. The conventional destinations used end up generating a low valuation of biomass, which is rich in macronutrients, the use of new technologies can generate significant changes in this scenario, creating by-products with greater added value. Therefore, the present work sought to analyze the use of pyrolysis as an alternative treatment for biomass, testing its efficiency, identifying its characteristics and designing its production in order to maximize bio-oil. The biomass used was characterized physically and chemically, through immediate analysis and acid digestion, the pyrolysis products were also characterized with the exception of non-condensable gases. The production of bio-oil, biochar and non-condensable gases through the pyrolysis treatment reached, the percentages (m/m) of 18.48 ± 0.55; 45.68 ± 1.55 and 35.84 ± 1.12 respectively. The characterization of the biochar showed that there are no significant losses in macronutrients in relation to the concentration of natural biomass. The characterization of the bio-oil showed that there are components that, if isolated, can generate a very high value for the biomass. The technical feasibility was confirmed through the optimization carried out in the laboratory and the final projection concluded that a gross profit can be reached 38 times greater than the current value.
