Title
(EN) BIOREFINERY PROCESS FOR EXTRACTION, SEPARATION AND RECOVERY OF FERMENTABLE SACCHARIDES, OTHER USEFUL COMPOUNDS, AND YIELD OF IMPROVED LIGNOCELLULOSIC MATERIAL FROM PLANT BIOMASS
(FR) PROCÉDÉ DE BIORAFFINERIE POUR L'EXTRACTION, LA SÉPARATION ET LA RÉCUPÉRATION DE SACCHARIDES FERMENTABLES, D'AUTRES COMPOSÉS UTILES, ET PRODUCTION D'UNE MATIÈRE LIGNOCELLULOSIQUE AMÉLIORÉE À PARTIR D'UNE BIOMASSE VÉGÉTALE
Abstract
(EN)
Non-food plant biomass is subjected to hot-water extraction in a pressurized vessel at an elevated temperature up to about 250° C and at a pH below about 7,0, to yield an aqueous extract containing hemicellulosic components, other wood-derived compounds, and a lignocellulosic residue, The separated aqueous extract or liquor is purified and concentrated through a multi-step process producing fermentable sugars. At each stage, inhibitory chemicals such as acetic acid, lignin, and furfural are separated and eventually recovered as commercial chemicals. The lignocellulosic residue may be further processed, as a material with enhanced resistance to sorption of water, for manufacture of improved: pulp and paper, construction materials, pellet fuel, and/or other useful products.
(FR)
Selon l'invention, une biomasse végétale non alimentaire est soumise à une extraction par de l'eau chaude dans un récipient sous pression à une température élevée allant à environ jusqu'à 250°C et à un pH au-dessous d'environ 7,0, pour donner un extrait aqueux contenant des composants hémicellulosiques, d'autres composés dérivés du bois et un reste lignocellulosique. L'extrait aqueux séparé ou liqueur aqueuse séparée est purifié(e) et concentré(e) à travers un procédé multi-étapes produisant des sucres fermentables. A chaque stade, des produits chimiques inhibiteurs tels que l'acide acétique, la lignine et le furfural sont séparés et en fin de compte récupérés sous la forme de produits chimiques commerciaux. Le résidu lignocellulosique peut encore être traité, comme matière ayant une résistance accrue à la sorption d'eau, pour la fabrication de produits améliorés: pâte et papier, matériaux de construction, combustible en pastilles et/ou produits utiles plus huileux.
