  • Publication number: 20170183580
    Abstract: Methods are provided for producing lubricant base stocks from deasphalted oils formed by sequential deasphalting. The deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher severity of deasphalting. This can result in formation of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been included as part of a deasphalter rock fraction.

  • Publication number: 20160178132
    Abstract: In a process for the catalytic conversion of organic oxygenates to hydrocarbons, a feed comprising at least one organic oxygenate is contacted with a zeolite catalyst under conditions effective to produce a hydrocarbon product comprising aromatics, olefins and paraffins. At least a fraction of the hydrocarbon product containing C4+ hydrocarbons, including at least part of the olefins, is then contacted with hydrogen in the presence of a hydrogenation catalyst under conditions effective to saturate at least part of the olefins in the C4+-containing fraction and produce a hydrogenated effluent containing less than 1 wt % olefins. The hydrogenated effluent is useful as a diluent for heavy crude oils.

  • Patent number: 9290703
    Abstract: A diesel fuel product with beneficial cold flow properties can be produced. A suitable feedstock for forming a diesel boiling range product can be hydrotreated to have a sulfur content of at least about 100 wppm and then dewaxed. This two stage process can allow for production of an arctic or winter diesel without use of high pressures. Optionally, a divided wall column fractionator can be used to allow a single separation stage to handle the effluent from both the hydroprocessing and the dewaxing stages.

  • Publication number: 20150175911
    Abstract: Methods are provided for processing a gas oil boiling range feedstock, such as a vacuum gas oil, in a single reaction stage and/or without performing intermediate separations. The methods are suitable for forming lubricants and distillate fuels while reducing or minimizing the production of lower boiling products such as naphtha and light ends. The methods can provide desirable yields of distillate fuels and lubricant base oils without requiring separate catalyst beds or stages for dewaxing and hydrocracking. The methods are based in part on use of a dewaxing catalyst that is tolerant of sour processing environments while still providing desirable levels of activity for both feed conversion and feed isomerization.

  • Patent number: 8864975
    Abstract: Integrated hydroprocessing methods using high activity, low density catalysts are provided. The high activity catalysts allow for lower temperature operation, which reduces catalyst degradation, while the low density of the catalysts means a corresponding reduction in the amount of metal needed to fill a reactor volume. The methods allow for flexible processing of feedstocks with a variety of wax contents.

  • Patent number: 8864976
    Abstract: Integrated hydroprocessing methods using high activity, low density catalysts are provided. The high activity catalysts allow for blocked operation when processing lube range feedstocks of widely varying characteristics, such as wax content, without having to substantially change the configuration or operating conditions of the process train. Instead, the different feedstocks can be accommodated by varying the reaction temperature in the process train.

  • Patent number: 8852425
    Abstract: A divided wall column allows for fractionation of multiple streams while maintaining separate product qualities. Effluents from multiple stages of a reaction system can be processed in a single divided wall column.

  • Publication number: 20140291202
    Abstract: Methods are provided for dewaxing a distillate fuel boiling range feed to improve one or more cold flow properties of the distillate fuel feed, such as cloud point, with reduced consumption of hydrogen during the dewaxing process. The reduced hydrogen consumption is achieved by using a dewaxing catalyst with a reduced content of hydrogenation metals, such as a content of Pt or Pd of from about 0.03 wt % to about 0.35 wt %. A distillate fuel feed can be dewaxed to achieve a desired cloud point differential using a reduced metals content dewaxing catalyst under the same or similar conditions to those required for a dewaxing catalyst with higher metals content.

  • Patent number: 8557106
    Abstract: This invention relates to a process involving hydrocracking of a feedstream in which a converted fraction can exhibit relatively high distillate product yields and maintained or improved distillate fuel properties, while an unconverted fraction can exhibit improved properties particularly useful in the lubricant area. In this hydrocracking process, it can be advantageous for the yield of converted/unconverted product for gasoline fuel application to be reduced or minimized, relative to converted distillate fuel and unconverted lubricant. Catalysts and conditions can be chosen to assist in attaining, or to optimize, desirable product yields and/or properties.
