    Abstract: Provided herein are methods of producing synthesis gas (syngas) from a plastic 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.

    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.

    Abstract: Tires are co-fed into a solid fossil fuel such as coal and fed into an entrained flow partial oxidation gasifier. High concentrations of solids and tires in the solids stream can be stably obtained without significant impact on the feedstock stream stability and pumpability. A consistent quality of syngas can be continuously produced while stably operating the gasifier and avoiding the high tar generation of waste gasifiers and without impacting the operations of the gasifier. The subsequent syngas produced from this material can be used to produce a wide range of chemicals.
