  • Publication number: 20150367320
    Abstract: A method of forming the highly selective ultra-small pore amorphous adsorbent includes introducing an ion-exchange material to a sodium aluminosilicate zeolite such that an ion-exchanged zeolite forms, calcinating the ion-exchanged zeolite at a calcination temperature such that the ion-exchanged zeolite collapses and forms the decationized amorphous adsorbent, and introducing a back ion-exchange material to the decationized amorphous adsorbent such that the highly selective ultra-small pore amorphous adsorbent forms. The highly selective ultra-small pore amorphous adsorbent has a pore aperture size operable to permit carbon dioxide to adsorb into the amorphous adsorbent and operable to deny methane from adsorbing into the amorphous adsorbent.

  • Patent number: 8808534
    Abstract: A process for refining naphtha that results in an improved octane value in a subsequent gasoline blend. Certain embodiments include separating a naphtha feed into light naphtha and heavy naphtha; separating the heavy naphtha into a paraffin stream and non-paraffin stream; introducing the light naphtha to a first isomerization unit, introducing the paraffin stream to a second isomerization unit; introducing the non-paraffin stream to a reforming unit and combining the resulting effluents to form a gasoline blend. The resulting gasoline blend has improved characteristics over gasoline blends that are made without introducing the paraffin stream to a second isomerization unit.

  • Publication number: 20130283854
    Abstract: A method of using the natural gas storage facility to reduce the effect of diurnal demand on a natural gas source includes introducing natural gas into the natural gas storage facility, separating the natural gas into a heavy natural gas component and a light natural gas component, and retaining the components during a non-peak period of demand. The natural gas storage facility includes a guard bed system and an adsorption bed system. The method also includes releasing the heavy and light natural gas components, mixing them into a released natural gas component product and introducing it to the natural gas source during a peak period of demand.

  • Publication number: 20130261365
    Abstract: A method for the transalkylation of a heavy reformate is provided. The heavy reformate is contacted with a transalkylation catalyst and hydrogen gas in a transalkylation reactor to selectively convert the heavy reformate to a xylenes-rich product stream. Light alkanes produced during the reaction can be supplied to a steam cracker where they are converted to light olefins.

  • Patent number: 7097787
    Abstract: A method of partially oxidizing a feed gas comprises providing a reactor containing a catalyst, providing a gas distributor comprising a body having a plurality of channels therethrough and a plurality of outlets from said channels for distributing gas across the catalyst, feeding the feed gas and the oxygen-containing gas into the gas distributor and allowing the feed gas and the oxygen-containing gas to flow through the gas distributor and out through the outlets into contact with the catalyst. The gas distributor preferably comprises a micro-channel gas distributor, which can be assembled by providing a plurality of etched plates defining flow channels, and stacking and fusing the plates. The reactant gases can be mixed within the gas distributor or maintained separately until they have exited the gas distributor.

  • Publication number: 20050265920
    Abstract: The present invention relates to thermally stable supports and catalysts for use in high temperature operation, and methods of preparing such supports and catalysts, which includes adding a rare earth metal to an aluminum-containing precursor prior to calcining. The present invention can be more specifically seen as a support, process and catalyst wherein the thermally stable support comprises two rare earth aluminates of different molar ratios of aluminum to rare earth metal, and optionally, alumina and/or a rare earth oxide. More particularly, the invention relates to the use of noble metal catalysts comprising the thermally stable support for synthesis gas production via partial oxidation of light hydrocarbon (e.g., methane) with minimal deactivation over long-term operations and further relates to gas-to-liquids conversion processes.
