TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Plant: The thermal conversion plant comprises a containment device holding a molten metallic material, where the carbonaceous feedstock is fed into contact with the molten material in a predetermined manner to conduct gasification of the feedstock into a gas stream intermediate product. The thermal conversion plant injects atmospheric air into the molten metallic material to produce gas stream intermediate product of a predetermined CO to H2 composition; or periodically injects atmospheric air into the molten metallic material to produce a gas stream intermediate product of a predetermined CO to H2 composition.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The method for production of Fischer-Tropsch hydrocarbon products onboard a marine vessel, from at least one gas, liquid or solid, carbonaceous feedstock, involves conducting gasification in a thermal conversion plant operationally connected to an onboard power plant unit and forming Fischer-Tropsch hydrocarbons in a Fischer-Tropsch reactor, where the thermal conversion plant sends a gas stream intermediate product from the thermal conversion plant to the Fischer-Tropsch reactor. The process for producing a hydrocarbon product from a carbonaceous feedstock is implemented onboard a marine vessel subsequently distributing the hydrocarbon product to at least one remote site and comprising a predetermined mass of metal onboard a marine vessel. The method involves heating the metal mass into a molten metal; holding the molten metal in a containment vessel, where the marine vessel collects ambient air and introduces the ambient air into contact with the molten metal; introducing a carbonaceous feedstock into contact with the molten metal; producing and yielding intermediate gas stream from the molten metal; collecting the intermediate gas stream and subjecting it to a chemical catalytic reaction to yield a predetermined hydrocarbon product; collecting the hydrocarbon product onboard the marine vessel; and distributing the product to at least one remote site. Preferred Components: The gas stream intermediate product comprises CO and H2 gas. EXAMPLE - No suitable example given.
