  • Patent number: 11873451
    Abstract: Compositions based on effluents and/or products from FCC processing of a high saturate content, low heteroatom content feedstock are provided. By processing a high saturate content, low heteroatom content feed under various types of FCC conditions, a variety of compositions with unexpected compositional features and/or unexpected properties can be formed. The unexpected compositional features and/or unexpected properties can correspond to features and/or properties associated with one or more of the total effluent, a naphtha boiling range portion of effluent, a distillate or light cycle oil boiling range portion of the effluent, and/or a bottoms portion of the effluent.

  • Patent number: 11597885
    Abstract: Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.

  • Patent number: 11566188
    Abstract: Method of refining whole crude oil or a wide cut crude oil, the methods comprising a combination of a hydrotreating reactor, a distillation tower, and an optional flash evaporation separator. The methods can also include light ends processing, fluid catalytic cracking, reforming, hydrocracking, and demetalization. In some methods a whole crude oil is first processed through a flash evaporation separator to create a wide cut crude oil and in other methods, the flash evaporation separator is not used as the whole crude oil is first treated in a hydrotreater.

  • Publication number: 20220403258
    Abstract: Systems and methods for producing an isomerization product. One or more isomerization reactors comprising a catalyst may be used to process an isomerization feedstock comprising a primary n-paraffin reactant and hydrogen gas, and the isomerization reactor may be operated at a pressure parameter at which the partial pressure of the primary n-paraffin is within about 70% to about 130% of its equilibrium vapor pressure to isomerize the primary n-paraffin reactant.

  • Publication number: 20220402838
    Abstract: Isomerization of normal paraffins to form branched paraffins may be complicated by significant cracking of C7+ paraffins under isomerization reaction conditions. This issue may complicate upgrading of hydrocarbon feeds having significant quantities of heavier normal paraffins. Cracking selectivity may be decreased by combining one or more naphthenic compounds with a feed mixture comprising at least one C7+ normal paraffin and/or by utilizing tungstated zirconium catalysts having decreased tungsten loading. Further, C5 and C6 normal paraffins may undergo isomerization in the presence of C7+ normal paraffins.

  • Patent number: 11441089
    Abstract: Distillate boiling range and/or diesel boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. This unexpected combination of properties is characteristic of crude oils that can be fractionated to form distillate/diesel boiling range compositions that can be used as fuels/fuel blending products with reduced or minimized processing. The resulting distillate boiling range fractions and/or diesel boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight and/or volume ratio, a low but substantial aromatics content, and a low sulfur content.
