Caracterización del pasto mombaza como materia prima para producir bioetanol

Abstract: El objetivo de este estudio realizado en 2017 fue caracterizar el pasto mombaza (Megathyrsus maximus) para evaluar su potencial como materia prima para la producción de biocombustible líquido (bioetanol). La producción anual de biomasa, el poder calorífico, la composición química y el rendimiento teórico de bioetanol fueron determinadas en cuatro frecuencias de corte (30, 60, 90 y 120 d después del rebrote). Los datos se analizaron con el procedimiento GLM (SAS) y las medias de los tratamientos se compararon c… Show more

“…The highest hemicellulose concentration was found at 60 d and was 5.6, 3.3, and 3 % higher than the FC at 30, 90, and 120 d, respectively (p ≤ 0.05; Table 3). In grasses, hemicellulose constitutes 11 to 34 % of biomass, and concentrations similar to the present experiment have been reported in previous work, for example, 18.7 % in Napier grass (P. purpureum; Mohammed et al, 2015) and concentrations of 15 to 23 % in Mombaza grass (P. maximum) (Ventura-Ríos et al, 2021b). Hemicellulose is made up of six-and five-carbon sugars, hexoses, and pentoses, respectively.…”

“…However, research on plant physiology, pasture behavior, and chemical composition of this grass is limited, and for a better utilization, it is necessary to determine the optimum age of regrowth, where it reaches the highest biomass production and chemical composition. In Mexico, different cultivars of the genera Cenchrus (Ventura et al, 2021a), Megathyrsus (Ventura-Ríos et al, 2021b) and Urochloa (Santiago et al, 2016) have recently been evaluated to determine their agronomic performance, calorific value, immediate analysis, and production of fermentable sugars to obtain cellulosic ethanol. Therefore, the hypothesis of this research was to test if regrowth age influences the energy concentration of Cayman grass.…”
