POLYMERS, ARTICLES, AND CHEMICALS MADE FROM DENSIFIED TEXTILE DERIVED SYNGAS

Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of densified textile derived syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The densified textile derived syngas quality, composition, and throughput are suitable for produce a wide range of chemicals and polymers, including methanol, acetic acid, methyl acetate, acetic anhydride, and cellulose esters through a variety of reaction schemes in which at least a portion of the chemical or polymer originates with densified textile derived syngas.

Photoluminescence material and production method thereof

The present invention is related to a production method of a photoluminescence material by micro-plasma treatment for degrading plastic piece into multiple smaller molecular, a graphene quantum dot and the composite thereof. By using micro-plasma treatment, the production method provided by the present invention consumes very little energy and the processing steps is simple and efficiency without the existence of any organic solvent. The products obtained by the said treatment is high valued graphene quantum dot and graphene quantum dot composite with excellent photoluminescence ability for at least white, blue, green, cyan or yellow colors.

Method of producing a chemical pulp from a textile material which comprises cellulose and a molded body from the chemical pulp

A method of producing a chemical pulp from a textile material which comprises cellulose for manufacturing regenerated cellulosic molded bodies, wherein in the method the textile material is comminuted, at least a part of non-fiber-constituents of the comminuted textile material is separated from fiber-constituents of the comminuted textile material, at least a part of non-cellulosic fibers of the fiber-constituents is mechanically separated from cellulosic fibers of the fiber-constituents, at least a further part of the non-cellulosic fibers is chemically separated from the cellulosic fibers, and producing regenerated molded bodies from the chemical pulp based on the cellulosic fibers after mechanically separating and chemically separating.

PROCESSES AND STRUCTURES FOR RECYCLING CARPET AND PRODUCTS OF SUCH PROCESSES

Methods and equipment for the recycling of carpet are disclosed that produce a clean fiber product suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester, polyolefin, or a polyamide, from carpets that includes a face fiber material, a polypropylene backing material, and an adhesive, and include the steps of mechanically impacting the carpet to break the bonds between the adhesive and the fibrous components, treating the fibrous components to remove adhesive granules from the fibrous components, and optionally separating the polypropylene backing from the face fiber. A clean adhesive/calcium carbonate product can also be produced from this process.
