  • Patent number: 12351654
    Abstract: High concentrations of recycle polymer are gasified in a partial oxidation gasifier to make a syngas useful to make a variety of chemicals and polymers, such as cellulose ester. Polymers such as cellulose esters can be made that are obtained from sustainable sources, recycle sources, and are biodegradable. Circularity in the manufacture of textiles and/or plastics made from the fibers of such cellulose esters can now be achieved. The process of making such a syngas from high concentrations of recycle polymer (e.g. textiles and/or plastics) includes campaigning for the production of syngas.

  • Publication number: 20240239920
    Abstract: 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.

  • Publication number: 20230211394
    Abstract: Chemical recycling facilities for processing mixed waste plastic are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy recovery facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

  • Publication number: 20230212469
    Abstract: Provided herein are methods of producing synthesis gas (syngas) from aplastic material. The methods generally comprise feeding a wet waste plastic and/or liquified plastic stream and molecular oxygen (O2) into a partial oxidation (POX) gasifier. The wet waste plastic generally comprises the plastic material mixed with a liquid medium and has a liquid content of at least 2 weight percent. The wet waste plastic may be in the form of a plastic-containing slurry and/or may be derived from other processes that produce plastic-containing streams. The wet waste plastic may also be combined with a quantity of coal (or pet coke) before being fed to the gasifier. A partial oxidation reaction is performed within the gasifier by reacting at least a portion of the plastic material and the molecular oxygen to form the syngas.
