A process for the pretreatment of lignocellulosic biomass, in particular during the production of ethanol from biomass. The process including a cooking step where the biomass is exposed to steam at elevated temperatures and pressures for a preselected period of time in a treatment vessel. During the process, volatile and liquid compounds are purged from the treatment vessel.
L'invention porte sur un procédé de prétraitement de biomasse lignocellulosique, en particulier pendant la production d'éthanol à partir de biomasse. Le procédé comprend une étape de cuisson dans laquelle la biomasse est exposée à de la vapeur à des températures et à des pressions élevées pendant une période de temps présélectionnée dans une cuve de traitement. Pendant le procédé, des composés volatils et liquides sont éliminés de la cuve de traitement.
