Determinación del poder calorífico de los residuos agroindustriales de cáscara de trigo y paja de cebada enriquecidos con nanopartículas de celulosa como una alternativa de energía

Abstract

The following Curricular Integration Work had the objective of determining the calorific value of wheat husk and barley straw enriched with cellulose nanoparticles in the laboratories of the Faculty of Sciences to use them as an alternative source of energy. For the analysis of the residues, the elemental analysis was extracted where carbon and nitrogen quantity tests were carried out in the laboratories of the GAIBAQ research group. For the proximal analysis, humidity tests were conducted by the hot air drying method and for ash, the muffle incineration method was used; it should be emphasized that these analyses were performed in duplicate and a manual briquetting machine was used to make the briquettes. Following these tests, the respective mixtures were made (50% wheat husk and 50% barley husk; 25% wheat husk and 75% barley husk and 75% wheat husk and 25% barley husk) and their calorific value was prolonged by means of a calorimetric pump. As a result, it was obtained that mixture number 2 has a high calorific value (40355.40 J/g) and from this mixture four combinations of 5%, 10%, 20% and 50% of cellulose nanoparticles are prepared. For the analysis of the results a statistical method was used, which showed that the hypothesis is negated since there was no increase in calorific value. It was concluded that the results of the combinations of mixture 2 and the nanoparticles are not effective since their calorific value was drastically decreased as compared to the initial calorific value. It is recommended that the agro-industrial residues had a humidity percentage lower than 5 % to obtain good results.
