Process for the treatment of biomass with steam in a sealed reactor at elevated temperature and pressure in a saturated steam environment comprising placing biomass in the reactor, sealing the reactor and heating the biomass until a temperature is reached in the range of 200-250 DEG C, keeping the biomass at that temperature for 2-20 minutes before allowing it to cool gradually to room temperature while maintaining a saturated steam environment, followed by opening the reactor and recovering the steam treated biomass; biomass obtained with the process; the use in the above process of a solution containing one or more metal salts in which the biomass is soaked before it undergoes the steam treatment; process for the conversion of the treated biomass into ethanol; ethanol obtained with the latter process; animal feed containing steam treated biomass and reactor for carrying out the process. |
