Abstract: The present disclosure relates to hydrocarbon pyrolysis of advantaged feeds. The advantaged feeds can comprise hydrocarbon, at least one halogen-containing composition, and at least one metal-containing composition, where the halogen-containing composition and the metal-containing composition are substantially different compositions. The disclosure encompasses steam cracking of advanced feeds comprising hydrocarbon and one or more of chloride-containing compositions, nickel-containing compositions, and vanadium-containing compositions.

Abstract: Processes for preparing a low particulate liquid hydrocarbon product are provided and includes blending a tar stream containing particles with a fluid to produce a fluid-feed mixture containing tar, the particles, and the fluid, and centrifuging the fluid-feed mixture at a temperature of greater than 60° C. to produce a higher density portion and a lower density portion, where the lower density portion contains no more than 25 wt % of the particles in the fluid-feed mixture.

Abstract: Hydrocarbon-containing fluids are provided for use during solvent-assisted hydroprocessing of pyrolysis tar, such as steam cracker tar. The hydrocarbon-containing fluids can be used at any convenient time, such as during start-up of a pyrolysis process when recycled liquid pyrolysis product is not available; when the amount of liquid pyrolysis product available for recycle is not sufficient to maintain desired hydroprocessing conditions; and/or when the changes to the quality of the liquid pyrolysis product reduce the suitability of the recycle stream for use as a utility fluid.

IPC: C10G69/06
Abstract: Systems and methods are provided for increasing the portion of a pyrolysis tar fraction that can be hydroprocessed by using a physical particle size reduction process on at least a portion of the pyrolysis tar fraction. The physical particle size reduction process can reduce the percentage of particles in the pyrolysis tar fraction that have a particle size of 75 μm or greater, or 50 μm or greater. It has been unexpectedly discovered that at least a portion of the particles having a size of 75 μm or less, or 50 μm or less, can be effectively hydroprocessed to form products of greater value while still reducing or minimizing the amount of fouling or plugging in a hydroprocessing catalyst bed. By increasing the number of particles having a size of 75 μm or less, or 50 μm or less, while selectively removing larger particles from the SCT fraction, a higher yield of hydrocarbon products can be achieved for a feed containing an SCT fraction. This can reduce or minimize the amount of particulates that are disposed of by incineration or another disposal method for fractions that have a lesser value.

Abstract: Copolyesters such as polyethylene terephthalate (PET) or polyethylene furanoate (PEF) modified with bifuran polyacids such as dimethyl-2,2′-bifuran-5,5′-dicarboxylate (BFE), 2,2′-bifuran-5,5′-dicarboxylic acid (BDA), or bis(2-hydroxyethyl)-2,2′-bifuran-5,5′-dicarboxylate (BHEB), and/or bifuran polyhydroxyls, may have improved properties such as glass transition temperature (Tg), tensile modulus, barrier properties, crystallinity, and/or impact strength. Polyethylene terephthalate-co-bifuranoate (PETBF) has an improved Tg. Also described are polyethylene furanoate-co-bifuranoates (PEFBF).

Abstract: This invention relates to a process for determining the suitability of pyrolysis tar, such as steam cracker tar, for upgrading using hydroprocessing without excessive fouling of the hydroprocessing reactor. A pyrolysis tar is sampled, the sample is analyzed to determine one or more characteristics of the tar related to tar reactivity, and the analysis is used to determine conditions under which the tar can be blended, pre-treated, and/or hydroprocessed.

IPC: C10G69/06
Abstract: This invention relates to thermally-treating and hydroprocessing pyrolysis tar to produce a hydroprocessed pyrolysis tar, but without excessive foulant accumulation during the hydroprocessing. The invention also relates to upgrading the hydroprocessed tar by additional hydroprocessing; to products of such processing; to blends comprising one or more of such products; and to the use of such products and blends, e.g., as lubricants, fuels, and/or constituents thereof.

Abstract: A process is described for upgrading pyrolysis tar, such as steam cracker tar, by hydroprocessing in the presence of a utility fluid. The hydroprocessing conditions comprise a pressure >8 MPa and a weight hourly space velocity of combined pyrolysis tar and utility fluid >0.3 hr−1 and are selected so that the hydrogen consumption rate is in the range of 270 to 445 standard cubic meters/cubic meter (S m3/m3) of pyrolysis tar.
