Resumen de: WO2025081925A1
Provided in the present invention is a pellet machine for processing biomass fuel, and a control method therefor. The pellet machine comprises a conditioner, a conveyor and a pressing unit which are sequentially arranged in series, wherein the pressing unit comprises a pressing casing, a ring die and a pressure roller assembly, and the pressure roller assembly comprises a pressure roller body and a shifting rod component; and an adjusting component connected to the pressure roller assembly. By means of providing the shifting rod component, during the process in which the ring die drives a pressure roller to rotate, the shifting rod component can be used to stir materials between the ring die and the pressure roller, such that the fluidity of the materials between the ring die and the pressure roller can be improved, and the materials in a deformation and compaction zone can also be reduced or prevented from flowing out towards a feeding zone when subjected to high-pressure squeezing, thus improving the pelleting efficiency and reducing energy consumption.

The invention provides an oligosaccharide debranching enzyme mutant and use thereof in a glucose mother liquor. The mutant is obtained by mutating valine at position 219 in SEQ ID NO: 1 into alanine. According to oligosaccharide debranching enzyme mutant V219A, a primary mother liquor, a secondary mother liquor, or a tail liquid after chromatographic separation is used as a substrate, the percentage contents of glucose in the products are 99.21% (primary mother liquor), 98.89% (secondary mother liquor) and 97.97% (tail liquid after chromatographic separation) respectively, which are 2.86%, 8.64%, and 28.67% higher than that of glucose obtained with the wild-type oligosaccharide debranching enzyme. Therefore, the mutant V219A obviously improves the percentage content of glucose in the glucose mother liquor, and the scope of application of the mother liquor can be expanded by the high product purity and substrate conversion rate, so the mutant V219A has higher industrial application value.

The present technology relates to biofuels, and more particularly, to biomass-based diesel from olefin oligomers. Diesel fuels with cetane number of 49 or greater are prepared by blending hydrocarbons produced by olefin oligomerization with renewable diesel, resulting in a blended fuel that has a lower cloud point than the cloud point of the renewable diesel. A different aspect relates to an integrated process for lipid HDO and olefin oligomerization wherein the propane coproduct of lipid HDO is subjected to dehydrogenation to produce a vapor stream having propylene and hydrogen. The propylene is subsequently oligomerized to iso-olefins and the iso-olefins are combined with the lipid feed for hydrogenation in the HDO reactor.
