    Abstract: Embodiments of methods and apparatuses for isomerization of paraffins are provided. In one example, a method comprises the steps of separating an isomerization effluent into a product stream that comprises branched paraffins and a stabilizer vapor stream that comprises HCl, H2, and C6-hydrocarbons. C6-hydrocarbons are removed from the stabilizer overhead vapor stream to form a HCl and H2-rich stream. An isomerization catalyst is activated using at least a portion of the HCl and H2-rich stream to form a chloride-promoted isomerization catalyst. A paraffin feed stream is contacted with the chloride-promoted isomerization catalyst in the presence of hydrogen for isomerization of the paraffins.

  • Patent number: 7838272
    Abstract: The present invention is generally directed to systems and methods for integrating gas-to-liquids (GTL) processing with biofuels production. In some embodiments of the present invention, carbon dioxide (CO2) generated by GTL processing is used to support grovel (via photosynthesis) of microalgae. In some such embodiments, the microalgae can be further processed to yield a diesel fuel that can be used either by itself, or mixed with fuel produced by the GTL processing.

  • Patent number: 7357836
    Abstract: In certain aspects, the invention features methods for forming crystalline membranes (e.g., a membrane of a framework material, such as a zeolite) by inducing secondary growth in a layer of oriented seed crystals. The rate of growth of the seed crystals in the plane of the substrate is controlled to be comparable to the rate of growth out of the plane. As a result, a crystalline membrane can form a substantially continuous layer including grains of uniform crystallographic orientation that extend through the depth of the layer.
