Abstract: Systems and methods are provided for upgrading catalytic slurry oil to form naphtha boiling range and/or distillate boiling range fuel products. It has been unexpectedly discovered that catalytic slurry oil can be separately hydroprocessed under fixed bed conditions to achieve substantial conversion of asphaltenes within the slurry oil (such as substantially complete conversion) while reducing or minimizing the amount of coke formation on the hydroprocessing catalyst. After hydroprocessing, the hydroprocessed effluent can be processed under fluid catalytic cracking conditions to form various products, including distillate boiling range fuels and/or naphtha boiling range fuels. Another portion of the effluent can be suitable for use as a low sulfur fuel oil, such as a fuel oil having a sulfur content of 0.1 wt % or less.

Abstract: Methods are provided for processing deasphalted gas oils derived from thermally cracked resid fractions to form Group I, Group II, and/or Group III lubricant base oils. The yield of lubricant base oils (optionally also referred to as base stocks) can be increased by thermally cracking a resid fraction at an intermediate level of single pass severity relative to conventional methods. By performing thermal cracking to a partial level of conversion, compounds within a resid fraction that are beneficial for increasing both the viscosity and the viscosity index of a lubricant base oil can be retained, thus allowing for an improved yield of higher viscosity lubricant base oils from a thermally cracked resid fraction.
Abstract translation: 提供了用于处理衍生自热裂化残渣馏分的脱沥青瓦斯油以形成组I，组II和/或组III润滑剂基础油的方法。 相对于常规方法，润滑剂基础油（任选地也称为基础油料）的产率可以通过以单程严重程度的中间水平热裂解渣油馏分来提高。 通过对部分转化水平进行热裂解，可以保留残渣部分中有利于提高润滑剂基础油的粘度和粘度指数的化合物，从而可以提高较高粘度的润滑剂基础油的产率， 热裂解渣油馏分。

Abstract: This disclosure relates to processes, compositions, and systems useful for the oxydehydrogenation of alkanes to form olefins (e.g., for the conversion of ethane to ethylene). The processes use an oxygen transfer agent and may be carried out in any suitable reactor, including a reverse flow reactor, a circulating fluid bed reactor, or a cyclic co-flow reactor.

Abstract: A reverse flow reactor (RFR) and process having a forward reaction feed cycle, a reverse reaction feed cycle, and a reverse regeneration cycle. The heat convected in the forward feed cycle matches the heat convected in the reverse flow cycles. Compared to an RFR without the reverse feed cycle, the three-cycle RPR substantially reduces the regeneration air flow rate, associated compression requirements, and the overall reactor volume, that are required.

Abstract: A method for producing pitch can include: hydroprocessing a challenged feed from a refinery operation to produce a hydroprocessed product; distilling the hydroprocessed product to yield one or more upgraded fractions and a resid fraction; and solvent deasphalting the resid fraction to yield a deasphalted oil stream and a hydroprocessed pitch stream. The resultant pitch can have a micro carbon residue (MCR) of 50 wt % or greater, a solubility in toluene of 95 wt % or greater, and a softening point of 200° C. or less. The pitch can optionally be fluxed with a fluxing solvent.
