摘要： An apparatus, for the steam explosion treatment of biomass, having a pressurized reactor vessel (20) to receive a biomass material (10) and steam (14), discharge lines (24) connecting the pressurized reactor vessel (20) to the separation device (30), the lines sized and positioned to allow for the steam explosion of biomass material (10). At the outlet end (27) of the discharge lines (24) is a collection-expansion manifold (26) to connect the outlet end (27) of each of the discharge lines (24) to a collection line (28), wherein the collection line (28) provides a passage for biomass material (10) and steam (14) flowing from the discharge lines (24). The collection line passage has a substantially larger internal cross-sectional area than the internal cross-sectional area of a single discharge line. The collection line (28) is coupled to a separation device (30) such that the separation device (30) receives the biomass material (10) and steam (14) from the collection line (28).

摘要： It is disclosed a process to transfer a ligno-cellulosic feedstock from a low pressure zone to a high pressure zone. A slurry the ligno-cellulosic feedstock is first provided, which is then subjected to a multi-step liquid, removal process comprising draining by gravity at least a portion of the free liquid; removing a first portion of the capillary liquid in a low pressure zone by continuously compressing a stream of the ligno-cellulosic feedstock to reach a moisture content in a first target range; removing a second portion of the capillary liquid by shearing and compressing the ligno-cellulosic stream in a plug forming device, to form a ligno-cellulosic feedstock plug having a moisture content in a second target range at an outlet of the plug forming device connected to the high pressure zone. In the removal of the first portion of the capillary liquid, at least one first compression device continuously compresses the stream of the drained ligno-cellulosic feedstock to a first control pressure, while conveying the stream of the drained ligno-cellulosic feedstock in a flow direction of a belt filter press.

摘要： A pretreated biomass is subjected to high frequency pulses and shear forces without denaturing and/or degrading the individual components of the biomass. The biomass is then subjected to compressive force to separate a first liquid fraction from a first fractionated biomass. The first fractionated biomass may again then be subjected to the same high frequency pulses and shear forces as previously, particularly if there are hemicellulose and/or sugars still present in the first fractionated biomass. Compressive forces are used to separate a second liquid fraction from a second fractionated biomass. The second fractionated biomass is subjected to oxidation. The second fractioned biomass is then subjected to compressive forces to separate out one or more water insoluble components of the biomass in water soluble form and to provide cellulose that has not been denatured and/or degraded and has a lignin contact of less than 7 percent.

摘要： The method of manufacturing cellulose nano-fibres from stalks of annual crops consist in that pieces of the stalks of annual plants are in sequence subjected to the action of steam, mechanical defibrillation, digestion in a digesting liquor, oxygen delignification in aqueous medium containing NaOH and MgSO4, bleaching with sodium chlorite done at least twice, alkaline extraction in an NaOH solution, enzymatic treatment of the prepared cellulose pulp by cellulase with 10-1000 J/g activity of endo-l,4-beta- glucanase 10-1000 J/g. After washing and enzyme deactivation, the aqueous suspension of the cellulose is put to homogenization and centrifugation to obtain a supernatant which contains cellulose nano-fibers.

摘要： Methods of processing lignocellulosic biomass to fermentable sugars are provided which rely on hydrothermal pretreatment. Soft lignocellulosic biomass feedstock is pretreated in a single-stage pressurized hydrothermal pretreatment to very low severity. The pre-treated biomass is hydrolysed, typically as a whole slurry, using enzymatic hydrolysis catalysed by an enzyme mixture comprising endoglucanase, exoglucanase, β-glucosidase, endoxylanase, and β-xylosidase activities at activity levels in nkat/g glucan of endoglucanase of at least 1100, exoglucanase of at least 280, β-glucosidase of at least 3000, endoxylanase of at least 1400, and β-xylosidase of at least 75, so as to produce a hydrolysate in which the yield of C5 monomers is at least 55% of the original xylose and arabinose content of the feedstock prior to pretreatment.
