摘要:
The invention relates to a method of making sugars comprising irradiating a layer of lignocellulosic material with a series of doses of radiation, using more than one electron beam device to deliver a total dose of radiation of at least 20 Mrad; and converting the irradiated material with an enzyme or micro-organism.
摘要:
The invention relates to a method of making a sugar or a combustible fuel by pre-treating a biomass feedstock comprising a cellulosic and/or ligno-cellulosic material by irradiation with electron beam radiation at a dose of between 10 Mrad and 150 Mrad; and by contacting said pre-treated biomass feedstock with one or more cellulolytic enzymes.
摘要:
The invention relates to a method of making an irradiated wood product, the molecular weight of the carbohydrate-containing material contained in said wood product being thus increased; as well as to an irradiated wood product.
摘要:
The invention relates to a method of producing a product comprising converting a biomass feedstock comprising a cellulosic and/or lignocellulosic material, pre-treated by irradiation, the conversion comprising contacting the feedstock with one or more micro-organism(s) selected from the group consisting of bacteria, fungi, plants, protists, thermophilic micro-organisms, and genetically engineered micro-organisms.
摘要:
The present disclosure relates to refining a product from a biomass containing chlorophyll and/or pheophytins. In particular, a method of refining a product (such as a biofuel) from a photosynthetic organism is disclosed. The photosynthetic organism can be a naturally occurring organism or a genetically modified or altered organism. The method of refining comprises removing nitrogen to obtain the desired product. In some aspects, nitrogen is removed from a chlorophyll and/or pheophytin containing product by enzymatic degradation of chlorophyll and/or pheophytins and subsequent removal of the nitrogen
摘要:
This invention relates to a process, a plant, and a biofuel for integrated biofuel production, such as with butanol, biodiesel, and/or sugar product. The integrated process includes the step of removing hexose from a feedstock to form a lignocellulosic material. The process also includes the step of converting the hexose to butanol and/or a biodiesel material, and the step of depolymerizing lignocellulosic material to form pentose and a residue. The process also includes the step of converting the pentose to butanol and/or a biodiesel material.
摘要:
The present invention refers to a fuel mixture that contains combustible solid powder and produced by mixing combustible solid powder and liquid fuel. It is in a simple way to make use of renewable biomass materials instead of fossil fuel for driving internal combustion engine to provide powder, in favor of saving fossil fuel resource. And an engine can use the fuel mixture.
摘要:
Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of elemental sulfur and optionally one or more alkylamine and/or one or more additional nucleophile to fragment and extract lignin. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation.
摘要:
A method is provided for hydrolyzing polysaccharides in a lignocellulosic feedstock to produce monosaccharides or pretreating a lignocellulosic feedstock, in which an aqueous slurry of the lignocellulosic feedstock is fed into a pressurized dewatering zone wherein the feedstock is partially dewatered and then is compressed into a plug. The plug is introduced into a reaction zone that operates at a pressure (P r ) equal to greater than about 90 psia and under suitable temperature and pH conditions to hydrolyze the polysaccharides or pretreat the feedstock. The plug provides a pressure seal between the outlet of the dewatering zone and the reaction zone. The pressure (P dwi ) of the aqueous slurry of the lignocellulosic feedstock at the inlet of the dewatering device is related to P r as follows: 0≤ΔP r - 20 psia) and 220 psia], and where ΔP is the absolute difference in pressure between P r and P dwi in psia.
