20090116711 | METHOD FOR TRANSCATHETER INTRA-ARTERIAL PERFUSION MAGNETIC RESONANCE IMAGING - A method to serially determine changes in perfusion to tissues is provided. This method involves injecting contrast material into a catheter that is positioned in the blood supply proximal to the targeted tissue of interest, acquiring a time series of images that depicts the uptake of this contrast material within the tissue, deriving semi-quantitative or quantitative perfusion metrics based upon the time series of perfusion images, altering perfusion to the targeted tissue by means of injecting pharmacologic agents or embolic agents into the blood vessels supplying the targeted tissue, repeating the acquisition of perfusion images to serially monitor changes in tissue perfusion after each alteration, and calculating changes in perfusion metrics after each series of perfusion images. This method is used to monitor changes in perfusion to various tissues, including a diverse array of tumors. The perfusion imaging method can be acquired using magnetic resonance, x-ray computed tomography, or radionuclide imaging. The perfusion metric is serially measured during an embolization procedure as a means of measuring changes in tissue perfusion or to target an endpoint based upon a specific alteration in the calculated perfusion metric. | 05-07-2009 |

20150231621 | TERMINAL ALKENE MONOISOMERIZATION CATALYSTS AND METHODS - The invention provides novel catalysts and methods of using catalysts for controlling the position of a double bond and cis/trans-selectivity in isomerization of terminal alkenes to their 2-isomers. Catalysts such as (pentamethylcyclopentadienyl)Ru formulas 1 and 3 having a bifunctional phosphine can be used in the methods. A catalyst loading of 1 mol % of formulas 1+3 can be employed for the production of (E)-2-alkenes at 40-70° C.; lower temperatures can be used with higher catalyst loading. Acetonitrile-free catalysts can be used at lower loadings, room temperature, and in less than a day to accomplish the same results as catalysts 1+3. The novel catalyst systems minimize thermodynamic equilibration of alkene isomers, so that the trans-2-alkenes of both non-functionalized and functionalized alkenes can be generated. | 08-20-2015 |

20150065768 | SYSTEMS AND METHODS FOR XYLENE ISOMER PRODUCTION - Methods and systems are provided for producing a xylene product. The method includes fractionating a feed stream in a feed fractionator to produce a feed bottoms stream and a feed overhead stream. The feed stream includes aromatic compounds and non-aromatic compounds, and more than 5 weight percent of the non-aromatic compounds have a boiling point above 105° C. at one atmosphere of pressure. The feed bottoms stream is de-ethylated in a heavy aromatics conversion zone to produce a de-ethylated aromatics stream and a light gases stream, where non-aromatic compounds are converted to light gases in the light gases stream. The de-ethylated aromatics stream is fractionated to produce a heavy aromatics stream and an intermediate aromatics stream, and a desired isomer stream is recovered from the intermediate aromatics stream and an isomerized stream in an isomer recovery process. The isomer recovery process produces an isomer raffinate stream, and the isomer raffinate stream is isomerized in an isomerization zone to produce the isomerized stream. | 03-05-2015 |
20150321976 | METHODS AND SYSTEMS FOR REFORMING AND TRANSALKYLATING HYDROCARBONS - Methods and systems for reforming and transalkylating hydrocarbons are disclosed. A method for processing a hydrocarbon stream includes the steps of separating para-xylene from a first mixed-xylene and ethylbenzene-containing stream to produce a first non-equilibrium xylene and ethylbenzene stream and isomerizing the first non-equilibrium xylene and ethylbenzene stream to produce additional para-xylene. The method further includes transalkylating a toluene stream to produce a second mixed-xylene and ethylbenzene-containing stream, separating para-xylene from the second mixed-xylene and ethylbenzene-containing stream to produce a second non-equilibrium xylene and ethylbenzene stream, and isomerizing the second non-equilibrium xylene and ethylbenzene stream using an ethylbenzene dealkylation type xylene isomerization process to produce additional para-xylene. | 11-12-2015 |
