Abstract: Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

Abstract: Systems and methods are provided for forming specialty products from hydrotreated FCC fractions. Optionally, the hydrotreated FCC fractions used for forming the specialty products can further include a (hydrotreated) portion of a steam cracker tar fraction. The specialty products that can be formed from hydrotreated FCC fractions include, but are not limited to, carbon blacks, resins, and carbon fibers. A convenient method for forming the hydrotreated FCC fractions can be fixed bed hydrotreatment.

Abstract: Systems and methods are provided for upgrading a mixture of catalytic slurry oil and coker bottoms by hydroprocessing. Optionally, the upgrading can further include deasphalting the mixture of catalytic slurry oil and coker bottoms to form a deasphalted oil and a deasphalter residue or rock fraction. The mixture of catalytic slurry oil and coker bottoms and/or the deasphalted oil can then be hydroprocessed to form an upgraded effluent that includes fuels boiling range products. Optionally, in some aspects where the feed mixture is deasphalted prior to hydroprocessing, the feed mixture can further include a portion of a (sour) vacuum resid.

Abstract: Systems and methods are provided for improving operation of a fluid catalytic cracker as part of an integrated processing environment including a deasphalting unit and a hydroprocessor. Optionally, a coker can be included in the integrated system to allow for further improvements. The improved processing can be facilitated based on a process configuration where a combination of deasphalting and hydroprocessing are used to perform conversion on more refractory compounds, so that the fluid catalytic cracker can be operated at lower severity conditions. This can allow for improved production of desirable olefins and reduced production of light paraffins and coke. Additionally or alternately, the processing configuration can allow the bottoms fraction from fluid catalytic cracking to be incorporated into a higher value use than the typical regular sulfur fuel oil disposition.

Abstract: Systems and methods are provided for upgrading blends of catalytic slurry oil and steam cracker tar to form fuel and/or fuel blending products. The steam cracker tar can optionally correspond to a fluxed steam cracker tar that includes steam cracker gas oil and/or another type of gas oil or other diluent. It has been unexpectedly discovered that blends of catalytic slurry oil and steam cracker tar can be hydroprocessed under fixed bed conditions while reducing or minimizing the amount of coke formation on the hydroprocessing catalyst and/or while reducing or minimizing plugging of the fixed bed, as would be conventionally expected during fixed bed processing of a feed containing a substantial portion of steam cracker tar. Additionally or alternately, it has been unexpectedly discovered that formation of coke fines within steam cracker tar can be reduced or minimized by blending steam cracker tar with catalytic slurry oil. This can facilitate fixed bed processing of the steam cracker tar, as after removal of particles the blend of catalytic slurry oil and steam cracker tar can maintain a reduced or minimized level of coke fines and/or other particles.

Abstract: Systems and methods are provided for fixed bed hydroprocessing of deasphalter rock. Instead of attempting to process vacuum resid in a fixed bed processing unit, vacuum resid is deasphalted to form a deasphalted oil and deasphalter residue or rock. The rock can then be hydroprocessed in a fixed bed reaction zone, optionally after combining the rock with an aromatic co-feed and/or a hydroprocessing solvent. This can allow for improved conversion of the deasphalter rock and/or improved combined conversion of the deasphalter rock and deasphalted oil.
Abstract translation: 提供脱沥青岩固定床加氢的系统和方法。 除了试图在固定床处理单元中处理真空渣油之外,还要将真空渣进行脱沥青以形成脱沥青油和脱沥青残渣或岩石。 然后可以在固定床反应区中加氢处理岩石,任选地在将岩石与芳族共进料和/或加氢处理溶剂组合之后。 这可以改善脱沥青岩石的转化率和/或改善脱沥青岩石和脱沥青油的组合转化率。
