Summary
Methanization ofEuphorbia tirucalli was determined under mesophilic and moderate thermophilic conditions. Three different plant pre-treatments were tested: ground, coarse chopped and dried and ground material. The batch digesters were fed at 5% dilution of dried matter. During a 35 days test, the best daily yield (0.78 l/l/d) was obtained with the chopped raw material under moderate thermophilic conditions.
Résumé
La méthanisation d'Euphorbiatirucalli a été réalisée en conditions mésophile et modérément thermophile. Trois différents pré-traitements de cette plante ont été testés: simple fragmentation, broyat, séchage puis broyage. Les digesteurs ont été alimentés avec 5% de matière sèche en batch. Lors d'une expérimentation de 35 jours, le meilleur rendement (0,78 l/l/j) a été obtenu avec les fragments de plante en condition thermophile modérée.
