Latest Patents

Hatano's latest patents include a process for coal-gasification and making pig iron. In this innovative method, a melting/gasifying furnace with a coke-filled layer is utilized. Coal is gasified by oxygen blown through tuyeres into a hot reducing gas, which ascends through the coke-filled layer to melt reduced iron. The resulting molten iron flows down through the coke-filled layer, where it is collected and discharged. The hot gas recovered from this process is then fed into a shaft reduction furnace to reduce iron ores. Additionally, various fuels, primarily comprising carbon and hydrogen, such as heavy oil and natural gas, are used for gasification.
