Abstract: Processes for upgrading a hydrocarbon for a predetermined period of time. The process can include determining an amount of one or more contaminant-containing compositions that will be present in a pyrolysis effluent based, at least in part, on a composition of a hydrocarbon feed to be steam cracked, a. temperature the hydrocarbon feed will be heated at during steam cracking, a residence time the hydrocarbon feed will be heated at the temperature during steam cracking, or a combination thereof. In some examples, the process can also include taking one or more steps to allow the hydrocarbon feed to be steam cracked for at least as long as a predetermined, period of time, such as controlling process conditions within one or more separation stages to favor certain product compositions and/or introducing a predetermined amount of one or more materials into various locations of the process, or any combination thereof.

Abstract: 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.-

Abstract: 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).

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.

Abstract: Processes and apparatus for preparing a liquid hydrocarbon product are provided. In one embodiment, a process for prepreparing a liquid hydrocarbon product includes thermally-treating a tar to produce a first tar composition and blending the tar composition with a utility fluid to form a tar-fluid mixture. The process includes separating the tar-fluid mixture to form a first lower-density portion and a first higher-density portion containing solids. The process further includes thermally-treating the first higher-density portion to form a thermally-treated first higher-density portion to convert at least a portion of the solids to liquid.

Abstract: Processes for preparing a low particulate liquid hydrocarbon product are provided and include blending a tar stream containing particles with a fluid and heating to a temperature of 250° C. or greater to produce a fluid-feed mixture that contains tar, the particles, and the fluid. The fluid-feed mixture contains about 20 wt % or greater of the fluid, based on a combined weight of the tar stream and the fluid. Also, about 25 wt % to about 99 wt % of the particles in the tar stream are dissolved or decomposed when producing the fluid-feed mixture.
