  • Publication number: 20140284251
    Abstract: A fuel desulfurization method is provided in the present invention. In the step (a), a fuel is oxidized by adding an ionic liquid, an oxidant, and an acid catalyst. In the step (b), the oxidized fuel is mixed with a desulfurization agent to form a desulfurized fuel. In the step (c), the ionic liquid is recycled. In the recycling step, a first solution is added into the ionic liquid. Then, a second solution is added into the ionic liquid to form a second solution phase and an ionic liquid phase. The second solution phase is separated from the ionic liquid phase. The first solution, the oxidant and the acid catalyst are removed from the remained ionic liquid phase to form a recycled ionic liquid.

  • 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: 7159740
    Abstract: A sample preparation system provides an automated process that dispenses appropriate amounts of solid material into wells of a microtiter plate for mixing into a suspension. The system utilizes an array of hollow tubes that are lowered into a particle reservoir such that particle material is forced up into the tubes. During loading, solid plungers in the tubes are positioned a known distance from the open end of the tubes. When the particle material is to be dispensed, the plungers are lowered to push the particle material out of the tubes and into receiving wells of the microtiter plate. The plunger stroke and internal diameter of the tubes defines the dispensed volume of particle material.

  • Publication number: 20040118750
    Abstract: A process is disclosed for the production of refinery transportation fuel or components for refinery blending of transportation fuels having a reduced amount of sulfur and/or nitrogen-containing impurities. The process involves contacting a hydrocarbon feedstock containing the above impurities with an immiscible phase containing hydrogen peroxide and acetic acid in an oxidation zone to selectively oxidize the impurities. After a gravity phase separation, the hydrocarbon phase containing any remaining oxidized impurities, is passed to an extraction zone wherein aqueous acetic acid is used to extract a portion of any remaining oxidized impurities. A hydrocarbon stream having reduced impurities can then be recovered. The acetic acid phase effluents from the oxidation and the extraction zones can then be passed to a common separation zone for recovery of the acetic acid and for optional recycle back to the oxidation and extraction zones.

  • Patent number: 5258117
    Abstract: A process for improving the performance of heavy oil refining units in a resid hydrotreating unit equipped for resid hydrotreating. The partially refined resid stream issuing from a train of ebullated bed reactor is first separated into high, medium, and low temperature components. The high temperature component is sent through a flash drum and then fractionated by solvent deasphalting in order to provide oil, resin, and asphaltene fractions. Thus, the asphaltene is eliminated before it can foul downstream equipment. This treatment of the heavy oil product has several benefits as compared to treating the vacuum tower bottoms. Among other things, one of these benefits is to debottleneck the resid hydrotreating unit, especially at the atmospheric tower.

  • Patent number: 5242578
    Abstract: A refining process uses a two or four stage solvent separator coupled to receive an incoming feedstream of low sulfur resid and a solvent. In the preferred two stage separator, the mixture at the top of the first separator stage is fed to the second stage separator via a heat exchanger. The mixture at the bottom of the first stage separator includes resins and asphaltenes which are fed to a hydrotreater and then, in turn, to a fractionator. The output from the bottom of this fractionator can be fed back to the resid feedstream of the first stage separator for recycled separation. The material at the top of the second stage separator is fed back through the heat exchanger where it helps heat the mixture fed from the top of the first to the second stage separator, this feedback recovers the solvent for reuse in the first stage. The material settling to the bottom of the second stage separator is fed into a catalytic cracker or processed elsewhere.
