Resumen de: WO2025118046A1
The present invention refers to a phosphorous-based composition to be used in ethanol/alcohol production, specifically used in the fermentation step, more particularly, such composition is suitable for improving the yeast metabolism in a fermentation process, thereby, increasing the ethanol yield production, without resulting in increased costs or modifications in the production process. A method for applying said composition in an ethanol process and the use of the composition are also described.
Resumen de: US2025188565A1
Improved processes and systems are disclosed for producing renewable hydrogen suitable for reducing metal ores, as well as for producing activated carbon. Some variations provide a process comprising: pyrolyzing biomass to generate a biogenic reagent comprising carbon and a pyrolysis off-gas; converting the pyrolysis off-gas to additional reducing gas and/or heat; reacting at least some of the biogenic reagent with a reactant to generate a reducing gas; and chemically reducing a metal oxide in the presence of the reducing gas. Some variations provide a process for producing renewable hydrogen by biomass pyrolysis to generate a biogenic reagent, conversion of the biogenic reagent to a reducing gas, and separation and recovery of hydrogen from the reducing gas. A reducing-gas composition for reducing a metal oxide is provided, comprising renewable hydrogen according to a hydrogen-isotope analysis. Reacted biogenic reagent may also be recovered as an activated carbon product. Many variations are disclosed.

Resumen de: US2024215601A1
Compositions including a vegetable- or animal-derived oil, such as fatty acid alkyl esters, are stabilized against oxidation using an oxygenated aminophenol antioxidant. The aminophenol includes one or two carbon-containing group(s) including a hydroxyl group and/or ether group separated from the N atom by one or more carbon atoms. The oxygenated aminophenol antioxidants effective at controlling oxidation at moderate and even low amounts, useful in a variety of different oil and methyl ester fatty acid preparations, and were effective at elevated temperatures, and performed significantly better than convention antioxidants.
