摘要： Improved processes and systems are disclosed for producing renewable hydrogen suitable for reducing metal ores, as well as for producing activated carbon. Some variations provide a process comprising: pyrolyzing biomass to generate a biogenic reagent comprising carbon and a pyrolysis off-gas; converting the pyrolysis off-gas to additional reducing gas and/or heat; reacting at least some of the biogenic reagent with a reactant to generate a reducing gas; and chemically reducing a metal oxide in the presence of the reducing gas. Some variations provide a process for producing renewable hydrogen by biomass pyrolysis to generate a biogenic reagent, conversion of the biogenic reagent to a reducing gas, and separation and recovery of hydrogen from the reducing gas. A reducing-gas composition for reducing a metal oxide is provided, comprising renewable hydrogen according to a hydrogen-isotope analysis. Reacted biogenic reagent may also be recovered as an activated carbon product. Many variations are disclosed.

摘要： Provided is a method for refining hot metal in a converter by dephosphorizing or decarburizing the hot metal while forming a burner flame at the leading end of a top-blowing lance to transfer the heat of the flame to the hot metal, thereby providing high heat transfer efficiency and productivity without the risk of heat-up or combustion in a channel in the top-blowing lance so that the content of a cold iron source such as iron and steel scrap can be increased.
A method for refining hot metal in a converter using a top-blowing lance 3 having a refining powder supply channel, a combustion oxidizing gas supply channel, and a refining oxidizing gas supply channel that are separate from each other includes supplying at least one of a lime-based flux, iron oxide, and a combustible material as a refining powder 29 from the refining powder supply channel to a surface of the hot metal using a fuel gas or a mixture of the fuel gas and an inert gas as a carrier gas while supplying a combustion oxidizing gas from the combustion oxidizing gas supply channel to form a flame below a leading end of the top-blowing lance, and supplying a refining oxidizing gas from the refining oxidizing gas supply channel to the surface of the hot metal.

where R denotes the pitch circle radius of the ejection openings of the refining oxygen gas blowing nozzle (mm),
r denotes the radius of the ejection openings of the burner nozzle (mm),
d denotes the diameter of the ejection openings of the refining oxygen nozzle (mm),
θ denotes the angle (inclination) between the axis of the refining oxygen gas blowing nozzle and the central axis of the circular orbit (°), and

摘要： The invention relates to methods and a device for decarbonising a steel melt (3) during the production of stainless steel in a metallurgical vessel (2), especially in a converter, whereby the steel melt (3) is treated with oxygen and optionally an inert gas, especially argon and/or nitrogen. During the decarbonisation of said steel melt (3) such that it has a carbon content of below 0.3 wt. %, oxygen and optionally inert gas, especially argon and/or nitrogen, are brought into contact therewith (3) by means of an opening beneath the surface of the steel melt (3) and a blowing device arranged above the surface of the steel melt (3).
