Title (EN) ALCOHOL MANUFACTURING PROCESS
(FR) PROCEDE DE FABRICATION D'ALCOOL
Abstract: front page image
(EN)A continuous process for the production of alcohol, preferably ethanol (130), from cellulosic materials (10). The cellulosic materials (10) are delignified such that the hemi-cellulose (34) and the cellulose (58) can be subsequently acid hydrolyzed (60) into simple sugars (76). These sugars are fermented (90) in the presence of yeast (88) to yield ethanol (110) and carbon dioxide (96). The alcohol vapor is removed from the fermentation solution under a reduced pressure and subsequently distilled (100). Carbon dioxide gas may be sparged throughout the fermenting solution (190) in order to aid in the removal of the alcohol from the fermenting solution. The gaseous carbon dioxide is captured and utilized in the manufacture of additional quantities of ethanol or other basic chemicals.
(FR)Procede de production d'alcool, en continu de preference de l'ethanol (130), a partir de materiaux de cellulose (10). Les materiaux de cellulose (10) sont delignifies de sorte que l'hemicellulose (34) et la cellulose (58) peuvent etre ulterieurement hydrolyses (60) en sucres simples (76). Ces sucres sont fermentes (90) en presence d'une levure (88) pour produire de l'ethanol (110) et de l'acide carbonique (96). La vapeur d'alcool est extraite de la solution de fermentation sous pression reduite puis elle est distillee (100). On fait barboter le gaz carbonique au travers de la solution de fermentation (90) de maniere a faciliter l'extraction de l'alcool de la solution de fermentation. Le gaz carbonique est recueilli et utilise dans la fabrication de quantites additionnelles d'ethanol ou autres produits chimiques de base.
