  • Process for the production of hydrocarbon fluids
    Patent number: 7311814
    Abstract: Hydrocarbon fluids are produced by hydrocracking a vacuum gas oil stream, fractionating and/or hydrogenating the hydrocracked vacuum gas oil. The fluids typically have ASTM D86 boiling point ranges within the range 100° C. to 400° C. the range being no more than 75° C., they also have a naphthenic content greater than 60%, the naphthenics containing polycyclic materials, an aromatic content below 2% and an aniline point below 100° C. The fluids are particularly useful as solvents, for printing inks, drilling fluids, metal working fluids and as silicone extenders.
    Type: Grant
    Filed: March 6, 2003
    Date of Patent: December 25, 2007
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Pierre-Yves Guyomar, Andre A. Theyskens
  • Hydrocarbon fluids
    Patent number: 7056869
    Abstract: Hydrocarbon fluids are provided which have ASTM D-86 boiling point ranges within 235° C. to 400° C. and a naphthenic content greater than 60%, the naphthenics containing polycyclic materials, the fluids preferably have an aromatic content below 2% and an aniline point below 100° C. The fluids are particularly useful solvents for printing inks, drilling fluids, metal working fluids and as silicone extenders.

  • Modified carbon or graphite fibrous percolating porous electrode, its use in electrochemical reactions
    Patent number: 4396474
    Abstract: This invention concerns a fibrous percolating porous electrode of the type containing a fibrous porous matrix made of carbon or graphite.The fibrous porous matrix, such as a carbon or graphite felt, is modified, for example by impregnation with a surface-active agent, and in the wetted state its apparent density in relation to water possesses specific values.
