Abstract: In some examples, a vapor phase product and a liquid phase product can be separated from a heated mixture that can include steam and a hydrocarbon. The liquid phase product can be catalytically cracked in the presence of a fluidized catalyst to produce a catalytically cracked effluent. A bottoms product can be separated from the catalytically cracked effluent. The bottoms product can be hydroprocessed to produce a hydroprocessed product. For example, the bottoms product can be hydroprocessed under pre-treater hydroprocessing conditions to produce a pre-treated bottoms product and the pre-treated bottoms product can be hydroprocessed under bottoms product hydroprocessing conditions to produce the hydroprocessed product. A hydroprocessor heavy product can be separated from the hydroprocessed product. The vapor phase product can be steam cracked to produce a steam cracker effluent. A tar product and an upgraded steam cracker effluent can be separated from the steam cracker effluent.

Abstract: A process for olefin oligomerization can include contacting a feedstock comprising Cn and C2n olefins/paraffins under oligomerization conditions in the presence of an oligomerization catalyst, wherein n is 2 to 15; and recovering an oligomeric product comprising C3n oligomers having a branching index of less than 2.1. Optionally, the feedstock can further comprise C3n olefins/paraffins.

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: In some examples, a vapor phase product and a liquid phase product can be separated from a heated mixture that includes steam and a hydrocarbon. The vapor phase product can be steam cracked to produce a steam cracker effluent. The steam cracker effluent can be contacted with a quench fluid to produce a cooled steam cracker effluent. The steam cracker effluent can be at a temperature of >300° C. when initially contacted with the quench fluid. A tar product and a process gas that can include ethylene and propylene can be separated from the cooled steam cracker effluent. The tar product can be hydroprocessed to produce a first hydroprocessed product. A hydroprocessor heavy product and a utility fluid product can be separated from the first hydroprocessed product. The quench fluid can be or include at least a portion of the utility fluid product.

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.

Abstract: Methods for upgrading a hydrocarbon feed are disclosed. The methods include a hydrocarbon feed having an insolubility number, Ifeed, with at least a first fluid to form a fluid-feed mixture; and inducing a centrifugal force to the fluid-feed mixture sufficient to form at least a higher density portion and a lower density portion, said lower density portion having an insolubility number, ILD, wherein ILD/Ifeed≦0.95. Methods and apparatus for hydroprocessing the treated feed and blending with a fuel oil blend-stock are also described.
