Determinación del poder calorífico de las cáscaras de piña y del bagazo de la caña de azúcar enriquecidos con nanopartículas de aluminio como alternativa de nuevas fuentes de energía

Abstract

The present research consisted of determining the calorific value of pineapple peels and sugarcane bagasse enriched with aluminum nanoparticles as energy sources. The methodology consisted of three combinations of the agroindustrial residues of sugarcane bagasse and pineapple peels, in proportions of: M1: 50-50%, M2: 75-25% and M3: 25-75%, respectively; consequently, the biomass with the highest calorific value content was combined with two concentrations of aluminum nanoparticles, 25 and 50% each, with three replicates. The starting point was a proximal chemical analysis of the raw material, dealing with: determining the percentage of moisture and the percentage of ash present, followed by an elemental analysis to determine the carbon and nitrogen content, a characterization of the aluminum nanoparticles by scanning electron microscopy and infrared spectrophotometry, to finally determine the calorific value, this was done by calibrating the calorimetric pump and subsequent corresponding procedure with the equipment, calculation of the data obtained and preparation of briquettes. A statistical analysis of variance with one factor with a significance level of 0.05 was used to test the hypothesis. The calorific value of pineapple peel was 40373.46 J/g and that of sugarcane bagasse was 24096.05 J/g, the M1 sample with a percentage of 50%-50% is the combination that favors the most to increase the calorific value of these agro-industrial wastes by adding 45808.97 J/g together; by adding the aluminum nanoparticles, the maximum value was 36492.48 J/g. The addition of aluminum nanoparticles did not increase the calorific value of these wastes; it is recommended to try other additions that could increase the calorific value.
