NOVELTY - Production of hydrocarbon products onboard a marine vessel (2), from at least one gas, liquid or solid, carbonaceous feedstock, involves conducting gasification in a thermal conversion plant operationally connected to an onboard powerplant unit and forming hydrocarbons in a chemical reaction plant, where the thermal conversion plant sends a gas stream intermediate product from the conversion plant to the chemical reaction plant.    USE - For producing hydrocarbon products onboard a marine vessel, from solid, liquid and gaseous carbonaceous feedstock and distributing the hydrocarbon products to remote site(s) (claimed); useful for producing hydrocarbon products such as methanol, light olefins, gasoline, diesel and heavy wax fuels, from variety of solid, liquid and gaseous feedstock carbonaceous feedstock such as biomass, municipal waste, municipal solid waste (MSW), scrap waste material, sludge, marine sludge, waste oil, waste sludge, scrap metal, wood, coal, lignite, waste coal, carbon black, rubber, scrap rubber material, rubber derived material, wood chips, charcoal, glass, paper, refuse derived waste, refused derived fuel (RDF), sand, soil material, granular particles, tar sands, shale oil, peat, natural gas, petroleum, crude oil, oil wax, sewage, grass, agriculture derived waste, and animal derived waste.    ADVANTAGE - The method uses marine vessel that simultaneously performs delivery of the predetermined product to a remote site while converting the carbonaceous feedstock into hydrocarbon product using the onboard thermal conversion plant, the chemical reaction unit and the marine vessel's system. The marine vessel having thermal conversion plant and chemical reaction unit, conducts replenishment of the feedstock while at the same time, distributing the hydrocarbon product to a second remote site. The water, or fluid, or seawater collected by the marine vessel is injected below the surface of the molten metal, causing rapid expansion of the water into steam within the molten metal. The feedstock is introduced into thermal contact with the molten melt by feeding the feedstock below the surface of the molten melt to ensure high quality syngas production, and at the same time, water, seawater, or a fluid is also introduced into contact with the molten melt by injection below the surface of the molten melt to ensure high quality syngas production. The steam, or separated hydrogen and oxygen aids in the gasification process alongside with the feedstock material to improve the syngas quality, or syngas hydrogen (H2) to carbon monoxide (CO) ratio composition/content percentage. The flow rate and volume of water to be injected is controlled by a processor to ensure that the operating temperature of the molten metal does not fall below a predetermined temperature range. Further, addition of the carbonaceous feedstock by itself into the molten metal raises the overall temperature of the molten metal, hence, periodical injection of water performs temperature regulation of the molten metal and at the same time provides steam or H2 for gasification of the feedstock to yield syngas of a particular quality.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing the hydrocarbon product from the carbonaceous feedstock the process implemented onboard the marine vessel, and the marine vessel subsequently distributing the hydrocarbon product to at least one remote site, involving providing a predetermined mass of metal onboard a marine vessel; heating the metal mass into a molten metal; holding the molten metal in a containment vessel; collecting fluid, water or seawater and introducing fluid, water or seawater into contact with the molten metal below its surface; introducing a carbonaceous feedstock into contact with the molten metal; producing and yielding an 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.
