Hf And Another Fluoride Patents (Class 585/842)
  • Patent number: 6303843
    Abstract: A process for removing sulfone from a liquid hydrocarbon containing a concentration of sulfone by mixing a liquid acid therewith and thereafter separating the resulting admixture into an acid phase and a hydrocarbon phase. The hydrocarbon phase has a concentration of sulfone less than such concentration in the liquid hydrocarbon.

  • Patent number: 6114593
    Abstract: A system and/or process for decreasing the level of at least one organic fluoride present in a hydrocarbon mixture by first passing the hydrocarbon mixture to an eductor and educting into the hydrocarbon mixture a catalyst comprising a volatility reducing additive and hydrofluoric acid to produce a hydrocarbon-catalyst mixture, permitting the hydrocarbon-catalyst mixture to undergo a phase separation to produce a hydrocarbon phase having a lower concentration of at least one organic fluoride than the hydrocarbon mixture and to produce a catalyst phase, and withdrawing at least a portion of the hydrocarbon phase to thereby form a hydrocarbon product stream, are disclosed. In an alternate embodiment, a system and/or process for controlling the concentration of at least one organic fluoride and/or the RON of the hydrocarbon mixture by adjusting the amount of volatility reducing additive present in the catalyst are disclosed.

  • Patent number: 5744685
    Abstract: A process is disclosed for the separation and recovery of an unsaturated hydrocarbon from its mixture with at least one other material by the selective and reversible complexation of the unsaturated hydrocarbon using a single cubane-type cluster of palladium, molybdenum and sulfur as a complexation agent.

  • Patent number: 5284993
    Abstract: Disclosed is a process for removing acid soluble oils, produced as an undesirable by-product of an acid catalyzed alkylation reaction, from a mixture containing a strong acid and methanesulfonic acid. The process includes the use of water to induce the formation of the two immiscible liquid phases of ASO and methanesulfonic acid with water. The two immiscible phases can subsequently be separated from each other.

  • Patent number: 4417091
    Abstract: Fluorinated impurities are removed from olefin oligomers by extraction with a solid adsorbent; the oligomers have been obtained from monoolefins having 2-4 carbon atoms, in the presence of a catalyst obtained by contacting a bivalent nickel compound with a hydrocarbyl aluminum halide and a trifluoroacetic acid.

  • Patent number: 4316998
    Abstract: HF is removed from hydrocarbon streams, e.g., a propane liquid stream from HF alkylation by water washing, the wash stream being contacted with solid caustic to remove moisture therefrom. The used wash water containing HF is combines with aqueous caustic obtained from said contacting and the admixture is used to contact HF acid soluble oil to remove HF therefrom. The thus, used aqueous stream separated from this last contacting is reacted with a calcium compound to form insoluble calcium fluoride and a supernatant aqueous liquid containing regenerated caustic. The regenerated caustic is used to remove the sulfur compounds from the alkylation hydrocarbons feed.
