Evaluación energética de biocombustibles sólidos elaborados a partir de mezclas de biomasa lignocelulósica

Abstract

the purpose of this work is to determine the energy capacity of solid biofuels (pellets) made from the mixture of lignocellulosic biomass. The residues used were peanut husk (Arachishypogaea) and corn stalk (Zea mays L.) present in different proportions in a total of five mixtures. The highest calorific value obtained (30534,89kJ / kg) was that of mixture 4 in proportions of peanut shell and corn stalk 25:75 respectively with an ash production of 9,49% and a fixed carbon content of 26,18% results that favor the efficiency of the pellet in the combustion process (Tmax = 787 ± 13°C) while the mixture 1 (100% peanut shell) obtained the lowest energy content (M1: 28191,06 kJ / kg) With the results obtained, it was determined that pellets made from mixed biomass have better properties than those manufactured by a single type of lignocellulosic residue.   Index Terms— ash, biomass, caloric power, fixed carbon, pellets.
