Resumen
El residuo de poda de olivo está siendo poco utilizado debido al alto coste de las alternativas existentes para su aprovechamiento, sin embargo, su gran potencial como fuente renovable para obtener biocombustibles o productos químicos abre otras alternativas para su valorización. En este presente Trabajo Fin de Máster se sugiere aprovechar la biomasa de poda del olivar mediante vía termoquímica, realizando un estudio completo de la primera etapa del proceso basada en un pretratamiento químico que emplea acetona como disolvente usando el microondas. Las condiciones óptimas obtenidas experimentalmente fueron: 66,5% (C), 6,6 min (t), 155,1 o C (T) y 0,052 (S/L). Estas condiciones condujeron a sólidos residuales con un elevado contenido en celulosa (98,9%), un mínimo porcentaje de lignina (0,8%), obteniendo así, una materia prima útil para llevar a cabo una hidrólisis enzimática y posterior fermentación para obtener biocombustibles y otros compuestos de interés.
The olive pruning residue is being little used due to the high cost of existing alternatives for its use, however, its great potential as a renewable source to obtain biofuels or chemicals opens other alternatives for its valorization. In this present Master’s thesis it is suggested to take advantage of the biomass of pruning of the olive grove by means of thermochemistry, carrying out a complete study of the first stage of the process based on a chemical pretreatment that uses acetone as a solvent using the microwave. The optimal conditions obtained experimentally were: 66.5% (C), 6.6 min (t), 155.1 oC (T) and 0.052 (S/L). These conditions led to residual solids with a high cellulose content (98.9%), a minimum percentage of lignin (0.8%), thus obtaining a useful raw material for enzymatic hydrolysis and subsequent fermentation to obtain biofuels and other compounds of interest.
