Abstract


Abstract: The waste generated by the apricot processing industry represents an interesting source for recovering industrial waste into renewable energy while eliminating this waste in order to contribute to the protection of the environment in the context of sustainable development. This work concerns the study of the apricot hydrolysis for bioethanol production; the residues are generated from the apricot processing industry. Different parameters have been optimized such as: the (mass / water) ratio (5%, 7.5%, 10%), particle size, etc. For such case, chemical pretreatment has been carried out using acid, oxidative and alkaline pretreatments with different concentrations (0.5%, 1%, 4%, 7%) (V/V) at a temperature of 80 °C. It has been found that the hydrolysis of lignocellulosic biomass using sulfuric acid (1%) led to the total sugars extraction of about 93.05 g/L.

Résumé : Les déchets issus de l’industrie de transformation de l’abricot présentent une source intéressante de déchets qui peuvent être valorisés en énergies renouvelables et leurs éliminations contribuent grandement à la protection de l’environnement. Ce travail concerne l’étude de l’hydrolyse des résidus d’abricot dans le but de produire un biocarburant en particulier, le bioéthanol. Différents paramètres ont été optimisés à savoir : le rapport (masse/ eau) (5% ; 7,5% ; 10%), la granulométrie des déchets, etc. Pour cela, des traitements chimiques ont été réalisés en utilisant des milieux alcalins, acides et oxydés à différentes concentrations (0,5%,1%, 4%, 7%) (V/V) à une température de 80°C. A l’issue de notre travail, l’hydrolyse de la biomasse lignocellulosique par l’acide sulfurique à 1% a permis de libérer jusqu’à 93,05 g/L de sucres totaux.
