Water-resistant, high-durability, and high-density biocarbon pellets are described. In some variations, a process for producing biocarbon pellets comprises: pyrolyzing a biomass-containing feedstock in a pyrolysis reactor, thereby generating a solid biocarbon-containing material and a pyrolysis vapor; introducing the pyrolysis vapor to a separation system configured to recover a pyrolysis condensate in liquid form separated from non-condensable gases; capturing pyrolysis condensate as a polyphenolic material; contacting the solid biocarbon-containing material with the polyphenolic material, thereby generating an intermediate mixture; introducing the intermediate mixture to a densification unit, thereby generating a biocarbon pellet precursor; and at least partially drying the biocarbon pellet precursor, thereby generating biocarbon pellets characterized by a 24-hour water uptake of about 20 wt% or less, measured at 25°C and 1 bar. The biocarbon pellets can be stockpiled outside, which is logistically convenient at manufacturing sites, such as industrial metal-making plants that feed the biocarbon pellets into the process.

A pyrolysis system using three different sections combined in series, of a vertical drying and gas scrubbing section, 2, a transitional section 3, and an extended horizontal high temperature reactor zone 4 based on top of a step grate furnace. The system is to efficiently convert various biomass materials into high Fixed Carbon material, clean syngas and valuable condensates by controlling feed down the vertical drying & gas scrubbing section in a packed bed-counter flow heat exchange arrangement where residence time and gas volume can be controlled through 3 feeding rate, 5 air injection, 6 & 14 recirculating gas injection. Radiant heat at 12 provides additional energy for drying the wet feed material.

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.

A method for characterizing the interaction force between lignin and cellulase is provided. The method includes the following steps: (1) preparation of lignin film: preparing a lignin solution, then dropwise adding the solution onto a silicon wafer, repeatedly spin-coating with a spin coater, and vacuum-drying the prepared lignin film; (2) AFM probe modification: modifying an AFM probe coated with a gold film on the surface with HS-PEG-COOH and then activating the carboxyl group, immersing the AFM probe after the carboxyl group activation in a PBS solution of cellulase for incubation, and after the modification is completed, placing the washed AFM probe in a PBS buffer solution for storage for later use; (3) testing the lignin-cellulase interaction force by using an AFM instrument in a liquid phase environment. AFM is used to quantitatively characterize the interaction between the cellulase and lignin in a liquid environment.

Resumen de: AU2023342163A1
A process is hereby provided for permanently (>1000 years) reducing carbon dioxide in the atmosphere. The process involves the cultivation of tree and plant waste (biomass), the conversion of the biomass in a reactor to a carbon product, e.g., charcoal, and subsequent storage of the carbon product. The reactor used for conversion is run at a low temperature, e.g., 300-450°C. Thus, there is negligible cracking. The product is primarily a solid carbon product, which is safe and can be easily handled. The carbon product can also be safely stored. In one embodiment, the carbon product is buried in a location that is tested for limited oxygen at burial depths. The permanence of the CO; reduction is therefore assured.
