摘要： A 5,5′-Di-(protected)-2,2′-bifuran:
wherein each R1 is independently an unsubstituted or substituted 5- or 6-member 1,3-dioxo-2-yl ring radical. Processes for making the bifuran include coupling 2-(protected)-furfural. Processes for using the bifuran include deprotection, functionalization, and/or polymerization to form a polyester. The polyester can be a renewable, high-performing polyester offering a combination of low cost of production, high sustainability, and excellent performance.-

摘要： 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. The invention includes establishing a reference activity for the thermally treating the pyrolysis tar to produce a treated tar having a lesser reactivity.

摘要： A hydrocarbon conversion process comprises providing a hydrocarbon feedstock comprising an effluent fraction from a pyrolysis process, wherein the effluent fraction has an initial boiling point at atmospheric pressure of at least 177° C. and a final boiling point at atmospheric pressure of no more than 343° C. and comprises at least 0.5 wt. % of olefinic hydrogen atoms based on the total weight of hydrogen atoms in the effluent fraction. The hydrocarbon feedstock is hydroprocessed in at least one hydroprocessing zone in the presence of treatment gas comprising molecular hydrogen under catalytic hydroprocessing conditions to produce a hydroprocessed product comprising less than 0.5 wt. % of olefinic hydrogen atoms based on the total weight of hydrogen atoms in the hydroprocessed product. The hydroprocessing conditions comprise a temperature from 150 to 350° C. and a pressure from 500 to 1500 psig (3550 to 10445 kPa-a).

摘要： Systems and methods are provided for co-processing of pyrolysis tar with pre-pyrolysis flash bottoms. In some aspects, the co-processing can correspond to solvent-assisted hydroprocessing. By combining pyrolysis tar and flash bottoms with a solvent, various difficulties associated with hydroprocessing of the fractions can be reduced or minimized, such as difficulties associated with hydroprocessing of high viscosity feeds and/or high sulfur feeds. Optionally, separate solvents and/or fluxes can be used for the pyrolysis tar and the flash bottoms. The resulting upgraded products can be suitable, for example, for inclusion in low sulfur fuel oils (LSFO).

摘要： 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, where the fluid-feed mixture contains about 30 wt % or greater of the fluid based on a combined weight of the tar stream and the fluid. The method also includes separating, e.g., by centrifuging, from the fluid-feed mixture 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, based on the weight of the particles in the fluid-feed mixture.

摘要： The present disclosure provides methods for hydroprocessing of heavy oils, such as pyrolysis tars. For example, a process for preparing a liquid hydrocarbon product includes providing a first process stream comprising a reduced reactivity tar, and blending the first process stream with a utility fluid to produce a second process stream comprising solids and a reduced reactivity, lower viscosity tar. The method can includes introducing the second process stream into a guard reactor without sulfiding the guard reactor catalyst(s) prior to introducing the second process stream into the guard reactor. The method includes hydroprocessing the second process stream in the guard reactor under mild hydroprocessing conditions to produce a third process stream. The method includes hydroprocessing the third process stream to produce a fourth process stream having a bromine number (BN) lower than 12 and comprising the liquid hydrocarbon product and the utility fluid.

摘要： 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.
