  • Patent number: 7485767
    Abstract: The present invention provides a process for producing synthesis gas blends which are especially suitable for conversion either into oxygenates such as methanol or into Fischer-Tropsch liquids. Such a process involves reforming of two separate gaseous hydrocarbon feedstreams (formed, for example, by dividing a natural gas feedstock) in a steam-reforming unit and an oxygen-blown reforming unit, respectively. The syngas effluent from each reforming unit is then combined, after appropriate pressure adjustments, to realize a synthesis gas blend containing selected amounts and ratios of H2, CO and CO2. In further invention embodiments, processes are provided for converting the resulting syngas blends into oxygenates or Fischer-Tropsch hydrocarbons. Further conversion of the oxygenates so produced into light olefins also constitutes part of this invention.

  • Patent number: 7396972
    Abstract: A method for producing an olefin stream is provided based on conversion of an initial natural gas stream into a synthesis gas. The resulting synthesis gas is enriched with CO2 previously separated from the natural gas stream. The synthesis gas is then used to form a methanol composition, which can then be used as feedstock for a methanol-to-olefin conversion reaction.

  • Patent number: 5387731
    Abstract: Disclosed is a process for removing hydrogenation by-products which comprises the use of an extractive distillation tower operated in combination with a solvent stripper, hydrocarbon purge and a water wash column. By the arrangement of the various feeds to and between the above mentioned, the green oil may be extracted away from desirable hydrocarbons.
