  • Sulfone removal from an oxidized hydrocarbon fuel
    Patent number: 8574429
    Abstract: A one-step process for desulfurizing an oxidized sulfone-containing fuel stream, such as a diesel stream, is disclosed where mass transfer and conversion of sulfone occurs simultaneously such that the sulfur atom in sulfone molecule is removed as sulfite to provide a low-sulfur diesel stream. The diesel stream for treatment is obtained as a result of the oxidation of a thiophene-rich diesel stream with an oxidant to provide a sulfone-containing diesel stream. The one-step process uses a single vessel having a shroud of vertical hanging fibers to affect the mass transfer of sulfones in diesel into contacting with an aqueous solution of alkali metal hydroxide where it is converted to sulfite and biphenyls. The sulfite-rich aqueous solution and low sulfur diesel are then separately removed from the vessel.

  • Catalysts and process for converting fuel gases to gasoline
    Publication number: 20040158113
    Abstract: A process for alkylation of olefin-containing gases with low molecular weight branched alkanes to generate alkylate. The process involves the use of solid acid catalysts as alkylation catalysts. In a specific embodiment, the process employs a three-phase catalytic reactor where olefins present in the gas are reacted, preferably to extinction, with a large excess of liquid branched alkane.
