METHOD FOR TREATING A LIGNOCELLULOSIC BIOMASS

Resumen de: US20260286398A1

A process for treating lignocellulosic biomass comprises: b) acidic or neutral pretreatment of the biomass to produce an acidic or neutral pretreated biomass,alternating withb′) basic pretreatment of the biomass previously placed under acidic, neutral or basic conditions to produce a basic pretreated biomass,followed byc) enzymatic hydrolysis of the acidic pretreated biomass and/or of the basic pretreated biomass, to obtain a hydrolyzed biomass,d) solid/liquid separation of the hydrolyzed biomass obtained at the end of step c) in the form of sugar(s) or a step of solid/liquid separation of the hydrolyzed biomass in the form of sugar(s) obtained at the end of step c) then treated in steps subsequent to the enzymatic hydrolysis step c), in order to obtain a separated juice and an unconverted solid residue, ande) recycling the solid residue to basic pretreatment step b′).

Provided are: genetically-modified Kluyveromyces marxianus that lacks inulinase and expresses a foreign protein; and a method for producing a foreign protein, the method comprising a step for culturing the genetically-modified Kluyveromyces marxianus.

CONVERSION OF A BIOMASS-DERIVED HYDROCARBON FEEDSTOCK INTO ACRYLATE SALTS

Resumen de: US20260285796A1

0000 The invention concerns a method and a plant for converting biomass into acrylate salts. 0000 The method successively involves: a) a step of treating the biomass to produce ethanol and CO<2>; b) a step of dehydrating the ethanol obtained at the end of step a) to obtain ethylene; c) a step of synthesizing acrylate salts from the ethylene obtained at the end of step b) and from the CO<2 >obtained at the end of step a).

PROCESS FOR THE PRODUCTION OF FERMENTATION PRODUCTS AND LIGNIN

Resumen de: EP4810620A1

A process for the production of one or more fermentation products and lignin. The method comprises pretreatment with sulfur dioxide and a volatile alcohol, chemical recovery, whole slurry saccharification, and fermentation. High monosaccharide yields are achieved, and alkoxylated and/or non-alkoxylated lignin fractions, as well as lignosulfonate, can be produced and separated if desired. Monosaccharides with or without lignin are subjected to fermentation to produce one or more fermentation products, for example, ethanol.

Resumen de: US20250163339A1

Production systems and methods for producing pellets or pellet products, which can be used, e.g., in an electric arc furnace (EAF) to produce metal alloys, are disclosed herein. In some embodiments, a method for forming coke pellets includes (i) blending biomass with a set of materials to form an input blend, (ii) preconditioning the input blend by hydrating the input blend to generate a first plurality of particles, (iii) charging the first plurality of particles into an oven to produce a second plurality of particles via pyrolysis, (iv) post-conditioning the second plurality of particles to produce a third plurality of particles by exposing the second plurality of particles to at least one of an amphipathic binder, a hydrophobic binder, or a hydrophilic binder, and (v) physically altering the third plurality of particles to form coke pellets. The biomass can have a first volatility and the set of materials can have a second volatility lower than the first volatility.
