摘要:
A method for washing biomass is described. The method includes: (i) receiving a first discrete amount of biomass; (ii) receiving a second discrete amount of biomass; (iii) washing the first discrete amount of biomass with solvent to produce a first effluent stream enriched with inorganic material; and (iv) washing the second discrete amount of biomass with the first effluent stream to produce a second effluent solvent stream.

Disclosed herein is a curing agent for epoxy resins that is comprised of the reaction product of an amine, an epoxy resin, and an elastomer-epoxy adduct. Additionally disclosed is a process comprising agitating a solution of an amine, an epoxy resin, and an elastomer-epoxy adduct as a dispersant at an elevated temperature in an organic medium.
摘要:
A finish for cellulosic fibrous substrates containing tertiary amine-containing polymers for providing durable control of body odors and the cellulosic materials treated with the finish, which materials exhibit little or no discoloration and little or no degradation of physical strength as a result of the treatment.
摘要:
A composition of biomass material is disclosed. The composition includes: (i) a lignocellulosic material; and (ii) at least one member selected from a group consisting of potassium, sodium and chlorides, wherein said at least one member comprising not more than about 0.01% (by weight) of said composition. The composition may not include more than 10% of water.
摘要:
A system for producing combustible biomaterial is described. The system includes: (i) a lignocellulose rupturing device for rupturing lignocellulose in biomass to produce a ruptured biomass material, the ruptured biomass material having an inorganic material; (ii) a washing subassembly designed to wash the ruptured biomass material having said inorganic material with a solvent and produce an inorganic-material-enriched solvent and an inorganic-material-depleted ruptured biomass; and (iii) a pyrolyzing subassembly for pyrolyzing the inorganic-material-depleted ruptured biomass to produce a combustible biomaterial.
摘要:
A curing agent for epoxy resins that is comprised of the reaction product of an amine, an epoxy resin, and an elastomer-epoxy adduct; compositions containing the curing agent and an epoxy resin; the compositions are useful in electronic displays, circuit boards, semi conductor devices, flip chips and other applications.
摘要:
Safety spectacles comprising a front and pivotally attached temples adapted to extend rearwardly from the front. Each temple has a portion recessed inwardly relative to an adjacent portion of the front to form a passage to the region behind the front for ventilation. The recessed temple portions extend forwardly of the rear edges of the front so as to overlap the adjacent portions of the front and thereby increase the degree of protection to the wearer.
摘要:
Polyolefin woven and nonwoven fibers, filaments and fabrics made therefrom which comprise a melt blend which comprises (a) a polyolefin; and (b) at least one compound of the formula (I) R1-(hydrophilic oligomer) (I) wherein R1 is a straight or branched chain alkyl of 22 to 40 carbon atoms and the hydrophilic oligomer is a homo- or co-oligomer consisting of monomer units derived from monomers selected from the group consisting of ethylene oxide, propylene oxide, ethylene glycol, propylene glycol, epichlorhydrin, acrylic acid, methacrylic acid, ethylene imine, caprolactone, vinyl alcohol and vinyl acetate; and wherein the hydrophilic oligomer consists of between 2 and 10 monomer units, exhibit excellent durable wettability. The fabrics are useful in disposable diapers, training pants, feminine napkins, tampons, incontinence care products, wet and dry wipes, wound dressings, surgical capes, filter medial, battery separators and the like.
摘要:
A process for optimizing values of profit or gross margin based on process parameters used to process fuel having a desired fuel property is described. The process includes: (i) receiving a predetermined value of a first property of a fuel derived from biomass; (ii) retrieving a first different sets of values of one or more process parameters associated with a process that converts biomass to fuel, and the first different sets of values of the one or more process parameters are based on the predetermined value of the first fuel property; (iii) generating estimated values for cost or revenue associated with the first different sets of values of the one or more process parameters; and (iv) identifying, from the first different sets of values, a first set of values of one or more process parameters that approaches an optimum profit or gross margin for the process.
