| 20090188839 | Removal of Peroxide Impurities from Naphtha Stream - A method and apparatus for removing peroxides from an exposed naphtha stream is shown and described. The process includes the catalytic reactive oxygen stripping of peroxides thereby generating hydrocarbons and oxygen. Numerous conventional catalysts may be employed. The catalytic stripping reaction can be carried out at substantially lower temperatures than conventional reboiled oxygen strippers thereby resulting in substantial energy savings. Further, the disclosed reactor vessels are substantially smaller and less expensive to build than conventional oxygen stripper columns. The disclosed energy efficient reactive oxygen stripping process and equipment is intended to be utilized upstream of a naphtha hydrotreating unit. | 07-30-2009 |

| 20100025303 | Application of microporous carbon adsorbent for reducing the benzene content in hydrocarbon streams - The present invention is related with the application of an adsorbent material of microporous carbon (MCA), prepared from the direct pyrolysis of copolymers generically known as Saran, in adsorption processes to reduce the benzene content in naphtha boiling range hydrocarbon streams, between 27 and 191° C., in which is preferable to perform a first separation by distillation of the C6's fraction, and a further separation of Benzene by adsorption through an adsorbent material bed, obtaining the fraction of C6's free of Benzene and an adsorbent with Benzene, which is further regenerated by pressure or temperature swing desorption or by displacement using a desorbent such as an inert gas at high temperature or by passing a desorbent which after the process, the desorbent and Benzene are separated by distillation. The fraction of C6's free of Benzene is reintegrated to the hydrocarbon stream and providing a gasoline with a Benzene content less than 1 volume %. Besides, the application of the MCA in this type of process allows obtaining Benzene with a minimum purity of 99.8 weight % and a maximum toluene content of 0.1 weight %, satisfying the specifications of ASTM D-2359-02 for Refined Benzene-535 | 02-04-2010 |

| 20090159505 | HEAVY OIL UPGRADE PROCESS INCLUDING RECOVERY OF SPENT CATALYST - A process to upgrade heavy oil and convert the heavy oil into lower boiling hydrocarbon products is provided. The process employs a catalyst slurry comprising catalyst particles with an average particle size ranging from 1 to 20 microns. In the upgrade process, spent slurry catalyst in heavy oil is generated as an effluent stream, which is subsequently recovered/separated from the heavy oil via a filtration assembly. The filtration assembly has a least a filtration unit employing at least a membrane for separating heavy oil from the catalyst particles. Valuable metals can be recovered from catalyst particles for subsequent re-use in a catalyst synthesis unit, generating a fresh slurry catalyst. | 06-25-2009 |

Such adsorbent is usefully employed for contacting with hydrocarbon mixtures to adsorb low-octane, linear and mono- or di-substituted alkanes therefrom, and thereby increase octane rating, e.g., of an isomerization naphtha raffinate. Adsorption processes and apparatus are also described, in which the carbon adsorbent can be utilized for production of higher octane rating hydrocarbon mixtures. | 01-30-2014 |
