NOVELTY - The containerized molten metal gasifier system comprises industrial standard organization (ISO) containers, where each ISO container includes an interior, an exterior and a container volume defined by outer dimensions of the container, a single molten metal gasifier unit installed in the interior of the ISO container and adapted to receive a feed material from inlet conduits that are present in operational communication with single molten metal gasifier unit to generate a product gas having carbon monoxide and/or hydrogen, and a motor device arranged in the ISO container.    USE - The containerized molten metal gasifier system is useful for the gasification of cellulosic biomass, coal and other types of carbonaceous feed to produce low British thermal unit syngas for downstream application such as electric power generation or chemical upgrading into determined syngas-derived product.    ADVANTAGE - The system ensures economic and energy-efficient gasification of cellulosic biomass, coal and other types of carbonaceous feed without any pollution.    DETAILED DESCRIPTION - The containerized molten metal gasifier system comprises industrial standard organization (ISO) containers, where each ISO container includes an interior, an exterior and a container volume defined by outer dimensions of the container, a single molten metal gasifier unit installed in the interior of the ISO container and adapted to receive a feed material from inlet conduits that are present in operational communication with single molten metal gasifier unit to generate a product gas having carbon monoxide and/or hydrogen, a motor device arranged in the ISO container adapted to introduce the feed material from inlet conduits into single molten metal gasifier unit, and a fluid pump arranged in each ISO container to introduce additional volume of cooling fluid to be admixed into vessels and/or to withdraw a part of determined volume of cooling fluid from vessels. The single molten metal gasifier unit is further adapted to melt and form a molten slag material to flow out from gasifier unit to slag outlet tubes that are present in operational communication with the gasifier unit. The slag outlet tubes are adapted to direct molten slag material to a slag granulation unit installed in the ISO container. The slag granulation unit comprises: vessels, where each vessel holds a determined volume of cooling fluid and slag outlet tubes that are present in fluid communication with determined volume of cooling fluid to cause cooling and granulation of molten slag material into granulated slag material; a cooling fluid inlet pipe present in fluid communication with determined volume of cooling fluid to cause additional volume of cooling fluid to be admixed into determined volume of cooling fluid; and a cooling fluid outlet pipe present in fluid communication with determined volume of cooling fluid to direct a part of determined volume of cooling fluid to be removed from vessels. Each ISO container is a 20 ft, 40 ft, 45 ft, 48 ft and/or 53 ft containers.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of the containerized molten metal gasifier system.
