摘要： It is disclosed a continuous process for pre-treating a ligno-cellulosic feedstock. The ligno-cellulosic feedstock is introduced in a pressurized reactor vessel and subjected to a hydrothermal treatment with steam by inserting steam from at least a two steam streams having different temperatures. The ligno-cellulosic feedstock is then subjected to steam explosion. Preferably, at least a portion of the steam in the reactor is superheated steam and the superheated steam is located in a superheated zone which is in proximity of the outlet of the pressurized reactor vessel.

摘要： A process for the pretreatment of lignocellulosic biomass is disclosed, which includes the steps of pretreating the lignocellulosic biomass to hydrolyze and solubilize hemicelluloses in the biomass; explosively decomposing the biomass into fibers; and extracting from the resulting solids fraction a liquefied portion of the lignocellulosic biomass before or after explosive decomposition. This removes compounds from the lignocellulosic biomass which are inhibitory to enzymatic cellulose hydrolysis and sugar fermentation to ethanol. For improved economy, the inhibitory compounds are not completely removed. The extraction step is controlled on the basis of the xylose equivalent content in the reaction mixture and the extracting step is discontinued once a xylose equivalent content of 4-8% w/w of xylose in the dry matter of the solids fraction is achieved. This most economically balances the practical need for inhibitory compound removal with the economical need to minimize the costs of the overall ethanol production process.

摘要： An energy efficient process for hydrolyzing lignocellulosic materials which comprises using a primary system by providing a start-up energy input to operating saturated steam conditions and thereafter operating the primary system with substantially constant energy input, the condition of the hydrolyzing saturated steam being controlled by water injection and/or steam bleeding from the primary system. The dwell time of the solids stream in the primary sustem is controlled by controlling its passage with flashing off of steam into a secondary system where drying occurs together with some small measure of hydrolysis in a lower pressure superheated steam environment, there being an energy input into the secondary system using steam bled from the primary system. The output solids material stream is preferably capable of being self polymerized into a formed shape eg a board.
