  • Patent number: 7799210
    Abstract: A three-step process of removing sulfur from naphtha feeds. The steps include a first hydrotreating step, a mercaptan removal agent and an adsorbent containing a reactive metal on an inorganic support. Step one removes at least 95 wt. % of the sulfur compounds while preserving at least 50 wt. % of the olefins. Treatment with the mercaptan removal agent lowers the sulfur content to 30 wppm total sulfur and final naphtha product contains leas than 10 wppm total sulfur.

  • Patent number: 7781629
    Abstract: A hydrotreating method uses two catalyst beds with the introduction, on the last catalyst bed, of oils of animal or vegetable origin for co-treating a mixture made up of oils of vegetable or animal origin and of petroleum cuts (gas oil cuts (GO) and middle distillates) in order to produce gas oil effluents meeting specifications with an improved cetane number. The first catalyst bed is dedicated to only the deep desulfurization reactions (HDS1) of a petroleum type feed. The effluents of the first catalyst bed having an effluent sulfur content below or equal to 50 mg/kg are separated into two streams. The first stream, which is predominant, is sent to the gas oil pool. The second stream is mixed with oils of vegetable or animal origin. The resultant oil-petroleum cut mixture is then subjected to a milder hydrotreatment (HDT2). The effluents obtained at the outlet of the second catalyst bed can optionally be mixed with the predominant stream from the first bed.

  • Publication number: 20100187160
    Abstract: Disclosed is a method for reducing the organic sulfur content in a sulfur-containing liquid fuel, wherein the sulfur-containing fuel is first brought in contact with a hydrogen-containing gas in a presaturator and subsequently the hydrogen-enriched liquid fuel is brought in contact with a suitable adsorbent in a reactor. The adsorbent is able to adsorb at least part of the sulfur and/or of the sulfur compound from the fuel at the surface. The contact with the adsorbent can advantageously take place not only at higher temperatures of approximately 400° C., but also at moderate temperatures, as low as room temperature, because the use of liquid fuel ensures very good contact between the fuel and the surface of the adsorbent, and therefore ensures reduction of the sulfur content.

  • Patent number: 7758745
    Abstract: A diesel desulfurization method has various steps including: implementing a modified oxidative desulfurization (UAOD) process. The UAOD has the steps of: mixing diesel fuel with room temperature ionic liquid, oxidant, phase transfer catalyst, and acid catalyst in a tank in a mix; recycling the ionic liquid and recycling the acid catalyst in aqueous phase. A step is to move the sulfur from the diesel fuel in a fluidized bed reactor (FBR) having bed reactor material. The process can be improved with ultrasound during mixing, or a high shear mixer. The bed reactor is preferably acidic alumina for adsorbing oxidized sulfur. The oxidant is preferably hydrogen peroxide (H2O2). The acid catalyst is preferably a mixture of Acetic acid and Tri-fluoro acetic acid.

  • Patent number: 7754652
    Abstract: A method and product for removing sulfur compound molecules from gasoline or diesel fuel includes exposing the gasoline or diesel fuel to a plurality of molecularly imprinted polymer beads (MIPS) that have receptor sites on the surfaces thereof that include imprints that match the physical shape of at least a portion of a sulfur compound molecule. A quantity of the sulfur molecules align with and adhere to some of the receptor sites and, accordingly, they are removed from the gasoline or diesel fuel producing a remediated or sweetened gasoline or diesel fuel. According to one embodiment, the MIPS are contained in an enclosure having a plurality of openings large enough to permit the solution to pass through and small enough so as to prevent the MIPS from passing through. According to another embodiment the MIPS are applied (i.e., coated) to the inside surface of a conduit and the gasoline or diesel fuel is forced or allowed to flow through the conduit thereby removing some of the sulfur molecules therefrom.
