摘要： Disclosed is a method of pretreating biomass in two pretreatment stages as part of a biofuel production process. The first stage pretreatment is carried out by heating the biomass to a first stage temperature of 140°C to 180°C for a first stage time of 30 minutes to 2 hours at a first stage pressure of 105 to 150 psig; and the second stage is carried out by heating the biomass to a second stage temperature of 190°C to 210°C for a second stage time of 2 to 10 minutes at a second stage pressure of 167 to 262 psig. The biomass may be initially conditioned prior to the first pretreatment stage by atmospheric steam heating and adjusting the moisture content of the biomass. Hemicellulose and inhibitors (inhibitory compounds) to downstream hydrolysis and fermentation are preferably removed between the first and second pretreating stages, more preferably after each pretreatment stage.

摘要： Disclosed is an improvement in a conventional process for C5 and C6 sugar recovery from lignocellulosic biomass for fermentation to ethanol, which process including the conventional steps of pretreatment of the biomass with steam at elevated temperature and pressure, collection of C5 sugars from hemicellulose breakdown, cellulose hydrolysis and collection of C6 sugars from cellulose breakdown. The improvement includes conditioning of the biomass prior to the pretreatment step by heating the biomass with steam for a time period between 5 minutes to 60 minutes to achieve a steam treated biomass having a temperature of about 80 to 100oC; and adjusting a moisture content of the steam treated biomass to about 45% to 80%. An increased recovery of C5 and C6 sugars is achieved compared to the conventional process

摘要： A prehydrolysis of wood chips or other lignocellulosic material in a vessel having a gaseous portion and a liquid portion. The vessel includes at least one stress relieving piece that inhibits overcompression of the lignocellulosic material. The vessel operates in a continuous process. A slurry of lignocellulosic material and liquid is removed from the bottom of the vessel.

摘要： The invention concerns a method, system and a withdrawal screen section for the impregnation of chips during the manufacture of chemical pulp. Chips are both steamed and impregnated in a low pressure impregnation vessel 3, using pressurised hot spent cooking liquor BL as the main part of the impregnation liquid, which hot spent cooking liquor produce most of the steam BLSτ necessary for steaming the chips. In order to improve the process in the impregnation vessel 3 are at least two independent first and second screen rows, SC1 and SC1 b respectively, installed. The first screen row withdraws acidified treatment liquor for disposal which otherwise would be a parasitic acidified waste fluid in the system, and the second screen row recirculates treatment fluid back to centre of treatment vessel in order to even out the pH profile over the cross section of the vessel.

摘要： The invention concerns a method, system and a withdrawal screen section for the impregnation of chips during the manufacture of chemical pulp. Chips are both steamed and impregnated in a low pressure impregnation vessel 3, using pressurised hot spent cooking liquor BL as the main part of the impregnation liquid, which hot spent cooking liquor produce most of the steam BL
ST necessary for steaming the chips.In order to reduce need for adding fresh steam for chip steaming is a first withdrawal section in the impregnation vessel 3 modified to be used both as a flash tank for warm pressurised wash filtrate as well as an improved wash-out feature for the spent impregnation liquid behind the screen in the withdrawal section. For this purpose is the withdrawal volume 60 arranged with an upper part 60a being located above the liquid level LIQ
LEV of the impregnation vessel, and an additional pressurised warm wash liquor REC
1 is added to the withdrawal volume, and steam flashed off is led in a steam duct 62 to the chip volume above the liquid level.
