    Abstract: The present invention provides a process for managing hydrogen in a hydrocarbon gas to liquid plant. The process includes passing a syngas feed stream produced by a partial oxidation reactor to a Fischer-Tropsch reactor, thereby converting the syngas to hydrocarbon liquids. The hydrogen management process further includes passing a second hydrogen rich stream produced by an auxiliary source to a hydrogen user such as an FT water stripper, an FT catalyst regeneration unit, and an FT product upgrading unit. The auxiliary source could be a process for converting hydrocarbons to syngas, a process for converting hydrocarbons to olefins, a process for converting hydrocarbons to aromatics, a process for catalytically dehydrogenating hydrocarbons, a process for catalytically cracking hydrocarbons, a process for refining petroleum, and a process for converting hydrocarbons to carbon filaments.

    Abstract: Methods are disclosed for preparing hydrothermally-stable structurally-promoted refractory-oxide catalyst supports, which includes mixing precursors of the refractory oxide and of at least one structural promoter and calcining the mixture. The methods feature the incorporation of at least one structural promoter into the lattice of a refractory-oxide material such as alumina. The hydrothermally-stable structurally-promoted refractory-oxide catalyst supports are useful in hydrothermal catalytic processes such as Fischer-Tropsch reactions.

    Abstract: Methods for producing clean liquid/wax products from a slurry used in a Fischer-Tropsch reactor are disclosed. In general, one embodiment of the present invention comprises a solid/liquid filtration system having a filter medium comprising a substrate and a filter cake deposited on the substrate, wherein the filter cake is generated by deposition of solids from the slurry. The thickness of the filter cake can be maintained within a desired range by controlling the slurry velocity and/or the pressure differential across the filter medium. This invention relates to a method of operation of such filtration system which increases filtration cycle time and improved filtrate quality resulting in very low solid content in filtrate.

    Abstract: The invention relates to methods for improving the octane number of a synthetic naphtha stream and optionally for producing olefins and/or solvents. In one embodiment, the method comprises aromatizing at least a portion of a synthetic naphtha stream to produce an aromatized hydrocarbon stream; and isomerizing at least a portion of the aromatized hydrocarbon stream to produce an isomerized aromatized hydrocarbon stream having a higher octane rating than the synthetic naphtha stream. Alternatively, the method comprises providing at least three synthetic naphtha cuts comprising a C4-C5 stream; a C6-C8 stream and a C9-C11 stream; aromatizing some of the C6-C8 stream to form an aromatized hydrocarbon stream with a higher octane number; steam cracking some of the C6-C8 stream and optionally the C9-C11 stream to form olefins; and selling some portions of C9-C11 stream as solvents. In preferred embodiments, the synthetic naphtha is derived from Fischer-Tropsch synthesis.

    Abstract: The present invention relates to a method and apparatus for reducing the maximum water concentration in multi-phase reactors operating at Fischer-Tropsch conditions. In a preferred embodiment of the present invention, a method of reducing the maximum concentration of water in a multi-phase reactor containing an expanded slurry bed and a water-rich slurry region for Fisher-Tropsch synthesis includes changing the flow structure of a predetermined region in the reactor. The flow structure may be changed by introducing a mixing enhancing fluid into the predetermined region, installing baffles into the predetermined region, or by other methods known in the art. Preferably the predetermined region is located between null H and H and between null R and R, where H is the height of the expanded slurry bed and R is the radius of the reactor.
