  • Publication number: 20210139620
    Abstract: A recycle content polystyrene and method of making a recycle content polystyrene wherein the recycle content is derived directly or indirectly from the cracking of recycle content pyrolysis oil and/or gas. The cracking of the pyrolysis oil can be conducted in a gas furnace or a split furnace.

  • Publication number: 20200248085
    Abstract: Pre-ground plastics of small particle size not more than 2 mm are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. High solids concentrations in the feedstock stream can be obtained without significant impact on the feedstock stream stability and pumpability. A consistent quality of 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 subsequent syngas produced from this material can be used to produce a wide range of chemicals.

  • Publication number: 20200248082
    Abstract: Pre-ground plastics of small particle size not more than 2 mm are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. A syngas composition can be made by charging an oxidant and a feedstock composition comprising recycle plastics and a solid fossil fuel to a gasification zone within a gasifier; gasifying the feedstock composition together with the oxidant in said gasification zone to produce said syngas composition; and discharging at least a portion of said syngas composition from said gasifier; wherein the recycled plastics are added to a feed point comprising a solid fossil fuel belt feeding a grinder after the solid fossil fuel is loaded on the belt, a solid fossil fuel belt feeding a grinder before the solid fossil fuel is loaded onto the belt, or a solid fossil fuel slurry storage tank containing a slurry of said solid fossil fuel ground to a size as the size fed to the gasification zone.

  • Publication number: 20200248084
    Abstract: Tires are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. High concentrations of solids and tires in the solids feedstock 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 while remaining within limits of an existing air permit on the gasifier. The subsequent syngas produced from this material can be used to produce a wide range of chemicals.

  • Publication number: 20200248083
    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.

  • Publication number: 20200247910
    Abstract: A process for preparing a recycle cellulose ester and a recycle cellulose ester composition and articles made with such recycle cellulose esters comprising at least one cellulose ester having at least one substituent on an anhydroglucose unit (AU) derived from recycled plastic content syngas are provided. The recycled plastic content syngas can be obtained by gasifying feedstocks containing a solid fossil fuel such as coal, a plastic, and water. The plastic can be post-consumer or postindustrial plastic.

  • Patent number: 6033447
    Abstract: Coal gasifiers using technology developed by Texaco Development Corporation, use coal slurry and oxygen as feed stocks. During start-ups, the raw gas produced in the gasifier must be flared until the downstream clean-up and recovery plants can be started. In order to reduce emissions through the flare during start-up, a technique was developed to start the gasifiers and downstream plants on a sulfur free, liquid, organic fuel. Once downstream plants are on-line, the fuel feed is switched to coal slurry on the same burner. The switch is accomplished while maintaining pressure and without interrupting to the fuel feed.
