Abstract: front page image
(EN)Systems and methods for increasing fermentation efficiency of a lignocellulosic hydrolysate are disclosed. The system comprises a filter configurable to remove matter having a particle size of larger than about 25 to 100 microns from the liquid component, and at least one nanofilter configurable to remove acids from the liquid component. An apparatus is used to adjust the pH of the nanofiltered liquid component using a calcium hydroxide composition to a pH of about 5.5 to 6.0. The calcium hydroxide composition includes calcium hydroxide alone or in combination with either ammonium hydroxide and/or potassium hydroxide. The biomass comprises lignocellulosic material including at least one of corncob, corn plant husk, corn plant leaves, and corn plant stalks.
(FR)L'invention concerne des systèmes et des procédés qui permettent d'augmenter l'efficacité de fermentation d'un hydrolysat lignocellulosique. Le système comporte un filtre configurable pour éliminer, du composant liquide, des matières ayant une dimension de particule supérieure à environ 25 jusqu'à 100 microns, et au moins un nanofiltre configurable pour éliminer des acides du composant liquide. Un appareil est utilisé pour ajuster le pH du composant liquide nanofiltré à l'aide d'une composition d'hydroxyde de calcium à un pH d'environ 5,5 jusqu'à 6,0. La composition d'hydroxyde de calcium comprend de l'hydroxyde de calcium seul ou en combinaison avec soit de l'hydroxyde d'ammonium et/ou de l'hydroxyde de potassium. La biomasse comporte une matière lignocellulosique comprenant au moins l'un parmi la rafle du maïs, les spathes du maïs, les feuilles du maïs et les tiges du maïs.
