  • Publication number: 20080281136
    Abstract: A catalyst composition and process facilitates the oxidative reforming of low molecular weight hydrocarbons, such as methane, to other hydrocarbons having 2 or more carbon atoms (“C2+ compounds”). Compositions having a formula comprising a metal, tungsten, manganese and oxygen effectively catalyze the oxidative reforming of methane with a high rate of conversion and selectivity. Controlling feed gas flow and catalyst bed temperature controls the exothermic OCM reaction, avoiding runaway reactions or coking. A single or multiple reactor system can be utilized for the oxidative reforming reactions. Using two reactors in series, catalyst embodiments produced favorable yields of C2+ compounds, in the presence or absence of a distributed oxygen feed, and with or without interstage effluent cooling. Removal of desirable end products from the reactor effluent, followed by recycling of the residual effluent, increases the conversion to, and ultimate yield of desirable end product.

  • Publication number: 20040238409
    Abstract: A process for the hydrogenation of a hydrocarbon feed includes contacting a major amount of the hydrocarbon feed with hydrogen in a counter-current manner in a first reaction zone under hydrogenation reaction conditions in the presence of a hydrogenation catalyst in at least a first catalyst bed wherein a liquid effluent exits at a bottom end of the first reaction zone and a hydrogen-containing gaseous effluent exits at a top end of the first reaction zone, and contacting a minor portion of the hydrocarbon feed with said hydrogen-containing gaseous effluent in a co-current manner in a second reaction zone having a catalyst bed positioned to receive the hydrogen-containing effluent of the first reaction zone.

  • Publication number: 20040192985
    Abstract: This invention provides for a process for hydrocarbon conversion in which a partially dehydrated hydrocarbon feedstock is contacted with at least two different molecular sieve materials, including a first molecular sieve having a Si/Al molar ratio of less than about 5 and a second molecular sieve having a Si/Al molar ratio of greater than about 5. Also, this invention includes such processes in which such feedstocks are contacted with a first molecular sieve having pores of at least about 6 Angstroms and a second molecular sieve having pores of less than about 6 Angstroms.

  • Patent number: 6717024
    Abstract: A slurry Fischer-Tropsch hydrocarbon synthesis process for synthesizing liquid hydrocarbons from synthesis gas in a synthesis reactor also hydroisomerizes the synthesized hydrocarbon liquid, which comprises the slurry liquid, in one or more lift reactors immersed in the slurry body in the synthesis reactor. A monolithic catalyst is preferably used for the hydroisomerization, and slurry circulation up through the lift reactors from the surrounding slurry body, is achieved at least in part by the lift action of the hydroisomerization treat gas. Preferably, catalyst particles are also removed before the slurry contacts the catalyst. Hydroisomerization occurs while the synthesis reactor is producing hydrocarbons, without interfering with the synthesis reaction. A gas bubble reducing downcomer may be used to produce and feed the gas bubble reduced slurry into the lift reactor, thereby providing a hydraulic head assist in the slurry circulation up through and out of the lift reactor.

  • Patent number: 6703429
    Abstract: The present invention discloses a process for converting synthesis gas into hydrocarbonaceous products including the steps of: (a) subjecting a first portion of synthesis gas to a dual functional syngas conversion process to form a first effluent comprising a first hydrocarbonaceous product including aromatics and iso-paraffins; (b) subjecting a second portion of synthesis gas to a Fischer-Tropsch synthesis process to form a second effluent comprising a second hydrocarbonaceous product including linear paraffins and linear olefins; and (c) alkylating the linear olefins with the iso-paraffins to produce high octane gasoline range alkylate.

  • Patent number: 6649803
    Abstract: A slurry Fischer-Tropsch hydrocarbon synthesis process for synthesizing liquid hydrocarbons from synthesis gas in a synthesis reactor also hydroisomerizes the synthesized hydrocarbons in one or more external lift reactor hydroisomerizing loops outside of the reactor, but which are a part of the reactor. A monolithic catalyst is used for the hydroisomerization and slurry circulation between the synthesis reactor and one or more loops is achieved, at least in part, by the lift action of a hydrogen treat gas injected into each loop.
