A process for production of ethanol from lignocellulosic material

This invention relates to a process for production of ethanol from lignocellulosic material. Lignocellulosic material treated with dicarboxylic acid, preferably with oxalic acid, separating hemicellulosic fraction to ferment pentose sugar. The lignin is dissolve in alkali, preferably with NaOH, sepa...

Beschreibung
Zusammenfassung:	This invention relates to a process for production of ethanol from lignocellulosic material. Lignocellulosic material treated with dicarboxylic acid, preferably with oxalic acid, separating hemicellulosic fraction to ferment pentose sugar. The lignin is dissolve in alkali, preferably with NaOH, separating cellulose fraction for further enzymatic treatment with one or more than one cellulytic enzymes capable of hydrolyzing cellulose. Enzyme hydrolyasate further subjected to fermentation in presence of ethanol producing yeast, preferably
