A process and apparatus for the enhancement of syngas (CO and H) to fuels production utilizing a carbon based feedstock, (for example coal) by exploiting some, or all, of the hot COproduced during the gasification step, and converting the COthrough electrochemical reactions into oxygen (O) and carbon via a molten salt reactor and directing the oxygen back to the gasifier to minimize or eliminate the need for an oxygen plant, while the carbon by-product (granular carbon) will be used for a variety of adsorbents for environmental applications.

A method of producing networks of low melting metal oxides such as crystalline gallium oxide comprised of one-dimensional nanostructures. Because of the unique arrangement of wires, these crystalline networks defined as 'nanowebs', 'nanowire networks', and/or &#x201c;two-dimensional nanowires&#x201d;. Nanowebs contain wire densities on the order of 10/cm. A possible mechanism for the fast self-assembly of crystalline metal oxide nanowires involves multiple nucleation and coalescence via oxidation-reduction reactions at the molecular level. The preferential growth of nanowires parallel to the substrate enables them to coalesce into regular polygonal networks. The individual segments of the polygonal network consist of both nanowires and nanotubules of &#x3b2;-gallium oxide. The synthesis of highly crystalline noncatalytic low melting metals such as &#x3b2;-gallium oxide tubes, nanowires, and nanopaintbrushes is accomplished using molten gallium and microwave plasma containing a mixture of monoatomic oxygen and hydrogen. Gallium oxide nanowires were 20-100 nm thick and tens to hundreds of microns long. Transmission electron microscopy (TEM) revealed the nanowires to be highly crystalline and devoid of any structural defects. Results showed that multiple nucleation and growth of gallium oxide nanostructures can occur directly out of molten gallium exposed to appropriate composition of hydrogen and oxygen in the gas phase. The method of producing nanowebs is extendible to other low melting metals and their oxides such as for example: zinc oxide, tin oxide, aluminum oxide, bismuth oxide, and titanium dioxide.

Novel methods and devices for production of liquid hydrocarbon products from gaseous reactants are disclosed. In one aspect, a method for separating a liquid hydrocarbon, typically a wax, from a catalyst containing slurry is provided, comprising passing the slurry through at least one downcomer extending from an overhead separation chamber and discharging into the bottom of a slurry bubble column reactor. The downcomer includes a cross-flow filtration element for separating a substantially particle-free liquid hydrocarbon for downstream processing. In another aspect, a method for promoting plug-flow movement in a recirculating slurry bubble column reactor is provided, comprising discharging the recirculating slurry into the reactor through at least one downcomer which terminates near the bottom of the reactor. Devices for accomplishing the above methods are also provided.
