  • Patent number: 6471852
    Abstract: The present invention is a process to reduce the fouling of equipment for processing petroleum feedstreams. The fouling is reduced by reducing the presence of peroxides and hydroperoxides in the feedstream. The steps of the process include mixing the feedstream with an aqueous phase containing a base and a phase transfer catalyst. The base reacts with the peroxides and hydroperoxides. The oil phase can then be further processed with minimum fouling of the equipment. The aqueous phase is recycled for reacting with fresh petroleum feedstream.

  • Patent number: 6420063
    Abstract: The invention discloses methods of producing thermally stable mesoporous transition metal oxide compositions by aqueous co-assembly of glycometallates and metal complexes with a surfactant template, without the necessity of the use of stabilizers. Mesoporous (nickel/platinum)-yttria-zirconia materials are also disclosed for use as electrode materials in solid oxide fuel cells. These materials display the highest surface area of any form of (metal)-yttria-stabilized-zirconia, thereby providing significant improvement in the efficiency of solid oxide fuel cells.

  • Patent number: 6362123
    Abstract: A hydrocracking catalyst is provided that includes a crystalline molecular sieve material component having a faujasite structure and an alpha acidity of less than 1, preferably 0.3 or less, and a dispersed Group VIII noble metal component. The extremely low acidity allows selective hydrocracking of the aromatic and naphthenic species in a feedstock, while limiting the cracking of paraffins. The catalyst produces improved yields of products, such as diesel fuel, at high conversion rates and with high cetane values.

  • Patent number: 6303019
    Abstract: The present invention is a process to reduce the fouling of equipment for processing petroleum feedstreams. The steps of the process include mixing the feedstream with an aqueous electrolyte forming an oil-in-water dispersion, passing the dispersion through an electrochemical cell, passing a low voltage current through the dispersion, and separating the phases of the dispersion. The oil phase can then be further processed with minimum fouling of the equipment. The water phase is recycled for dispersing fresh petroleum.

  • Patent number: 6223133
    Abstract: The present invention is a method for optimizing multivariate calibrations such as those used on FT-IR analyzers. The method involves the selection of an optimum subset of samples to use in the calibration from a larger set of available samples. The subset selection is done so as to minimize the bias of the resulting calibration while simultaneously maintaining acceptable standard errors and ensuring maximal range for the model.
