  • Patent number: 9803154
    Abstract: Disclosed herein is a process for preparing an isomeric mixture comprising a major amount of a para-branched mono-alkyl-substituted hydroxyaromatic compound.
    Type: Grant
    Filed: October 31, 2014
    Date of Patent: October 31, 2017

  • Publication number: 20170158976
    Abstract: A sulfidic complexing agent is disclosed that includes a suspension or a solution formed by a reaction between a water-soluble metal compound and a water-soluble sulfidic compound. The sulfidic complexing agent has a pH of from about 5 to about 11 and a molar ratio of metal to sulfur of from about 0.1 to about 1,000. The sulfidic complexing agent is useful for removing elemental mercury from a hydrocarbon fluid by contacting the hydrocarbon fluid with the sulfidic complexing agent. The molar ratio of sulfur in the sulfidic complexing agent to mercury in the hydrocarbon fluid is from about 50 to about 2,500. Also disclosed is a method for concurrently transporting and removing a trace amount of volatile mercury in a CO2-containing natural gas stream extracted from a subterranean formation. The natural gas stream is transported in a pipeline into which the sulfidic complexing agent is injected.

  • Patent number: 9193650
    Abstract: Processes for producing long chain secondary alcohols from fatty acids and fatty oils, wherein at least one fatty acid or a fatty acid mixture is contacted with a ketonization catalyst in a ketonization catalyst under ketonization conditions to provide a long chain ketone, and the long chain ketone is contacted with a selective ketone hydrogenation catalyst that lacks catalytic activity for alcohol dehydration to selectively hydrogenate the long chain ketone to provide the corresponding long chain secondary alcohol.

  • Patent number: 8927800
    Abstract: We provide a method for making hydrocarbon products with reduced organic halide contamination, comprising: a. separating an effluent from an ionic liquid catalyzed hydrocarbon conversion reaction into: i. a hydrocarbon fraction comprising an organic halide contaminant and from greater than zero to less than 5000 wppm olefins; and ii. a used ionic liquid catalyst fraction comprising a used ionic liquid catalyst; and b. contacting the hydrocarbon fraction with an aromatic hydrocarbon reagent and an ionic liquid catalyst to reduce a level of the organic halide contaminant to from greater than zero to 20 wppm in a finished hydrocarbon product.
