Systems and methods for processing coal for use in a direct air capture system

Embodiments discloses herein relate to methods of processing coal. A method to process coal includes subjecting raw coal to a liquefaction process effective to form a liquid pitch resin and subjecting the liquid pitch resin to a filtration process. The method further includes subjecting the liquid pitch resin to a low crystallinity spinning process to form a raw fiber. The raw fiber is then further subjected to a stabilization process configured to oxygen cross-link the fiber to form a stabilized fiber and then subjecting the stabilized fiber to a carbonization process to form a low thermal conductivity carbon fiber.

NANOFIBERS AND METHODS OF FORMING NANOFIBERS THEREOF

The present disclosure concerns nanofibers and methods of forming these nanofibers thereof. The method of forming nanofiber comprises providing 2D materials with charge bearing moieties on its planar surfaces and at its ends, reacting the charge bearing moieties on the planar surfaces with proton donors, proton acceptors, at least partially hydrophobic counterions or a second 2D materials with oppositely charge bearing moieties on its planar surfaces and at its ends in order to curl the 2D material, simultaneously reacting the charge bearing moieties at the ends with proton donors, proton acceptors, at least partially hydrophobic counterions or the second 2D materials with oppositely charge bearing moieties on its planar surfaces and at its ends, and crosslinking the neutralised charge bearing moieties at the ends in order for the 2D materials to interact with each other to form the nanofiber.

Antimicrobial and antifungal polymer fibers, fabrics, and methods of manufacture thereof

High-melting antimicrobial polymer fibers and antimicrobial fabrics comprising such fibers are prepared by preparing a masterbatch of polymer pellets (e.g., PET), silver and copper salts, and a compounding agent which provides free flowing polymer pellets which can be prepared in advance, with a long shelf life. Polymer masterbatches prepared by the methods of the invention can produce limited color or off-white antimicrobial fibers and fabrics using conventional melt spinning manufacturing methods. Fabrics incorporating fibers of the present invention are potent inhibitors of Athlete's foot fungi, gram negative and gram positive bacteria, and drug resistant pathogens.

For example, the methods for preparation can comprise: freezing a suspension comprising high aspect ratio microfibers; and freeze-drying the frozen suspension to obtain the aerogel.

RECYCLING METHOD OF WASTE FISHNET
20170088686 · 2017-03-30 ·

A recycling method of waste fishnet is provided. The waste fishnet is processed with steps of cutting, removing impurities, cleaning, and drying to form fishnet chips. The recycling method of waste fishnet includes the following steps. The fishnet chips are mixed with nylon-66, wherein the fishnet chips are of 70% by weight, and nylon-66 is of 30% by weight. The mixture is heated and molten. The molten mixture is then processed with the step of granulation. The grains are then processed with the step of spinning Thereby, the waste fishnet can be recycled and transferred into useful plastic materials.
