Resumen de: US20260241367A1
The present disclosure provides biorefining systems for co-producing activated carbon along with primary products. A host plant converts a feedstock comprising biomass into primary products and carbon-containing co-products; a modular reactor system pyrolyzes and activates the co-products, to generate activated carbon and pyrolysis off-gas; and an oxidation unit oxidizes the pyrolysis off-gas, generating CO2, H2O, and energy. The energy is recycled and utilized in the host plant, and the CO2 and H2O may be recycled to the reactor system as an activation agent. The host plant may be a saw mill, a pulp and paper plant, a corn wet or dry mill, a sugar production facility, or a food or beverage plant, for example. In some embodiments, the activated carbon is utilized at the host plant to purify one or more primary products, to purify water, to treat a liquid waste stream, and/or to treat a vapor waste stream.

Provided is a method for improving the yield of 1,3-butanediol from biosynthesis. The oxygen-depletion-induced endogenous promoter pfnF8 of Escherichia coli is used to drive the expression of key genes in a 1,3-butanediol synthetic pathway, and the expression of genes in the 1,3-butanediol synthetic pathway can be automatically induced by means of cell growth and changes in oxygen levels during the fermentation process, thereby balancing cell growth and the synthesis of 1,3-butanediol. In addition, the method does not require the addition of an exogenous inducer, thereby reducing production costs, and the method is suitable for large-scale industrial production.

The present invent provides improved rapid thermal conversion processes for efficiently converting wood, other biomass materials, and other carbonaceous feedstock (including hydrocarbons) into high yields of valuable liquid product, e.g., bio-oil, on a large scale production. In an embodiment, biomass material, e.g., wood, is feed to a conversion system where the biomass material is mixed with an upward stream of hot heat carriers, e.g., sand, that thermally convert the biomass into a hot vapor stream. The hot vapor stream is rapidly quenched with quench media in one or more condensing chambers located downstream of the conversion system. The rapid quenching condenses the vapor stream into liquid product, which is collected from the condensing chambers as a valuable liquid product. In one embodiment, the liquid product itself is used as the quench media.
