Increasing the weight of scrap steel can both improve energy recovery rate and reduce the consumption of auxiliary materials. However, due to the fluctuation in raw material conditions and the dispatch hysteresis of the scrap steel, conservative approaches are often adopted during the addition weight of the scrap steel. This study identified the key influencing factors of the scrap ratio in the converter and proposed a scrap addition principle based on molten iron conditions. To solve the problem of precise addition of scrap steel, this study proposed a combined scrap steel addition mode and established a burdening calculation model, making the weight of added scrap steel adjustable during the smelting process. This work can guide the energy in the furnace to converge towards the product and improve the energy recovery rate in the converter. The industrial experiments of this scrap steel addition mode showed that the average scrap ratio increased by 2.13%, the consumption of lime per ton of steel decreased by 1.5 kg/t, the consumption of iron ore per ton decreased by 1.52 kg/t, and the production of steel slag per ton decreased by 10.2 kg/t, significantly reducing costs and increasing efficiency.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":17160,"journal":{"name":"Journal of Sustainable Metallurgy","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agave bagasse biomass obtained from the Tequila industry has remarkable characteristics such as low S, N, and ashes contents, which are useful for the reduction of the ferrous minerals such as ilmenite (FeO∙TiO<sub>2</sub>). Reduction of ilmenite requires high temperatures and long residence times; coke is a common reductant but has elevated cost and limited reserves. Therefore, the reduction of ilmenite is a challenging process and the integration of renewable reductant sources such as agave bagasse offers a good alternative. This work focuses on reducing ilmenite by agave bagasse; the effect of temperature, residence time, and molar ratio of ilmenite:carbon from agave bagasse (I:AB) were assessed by X-ray diffraction, scanning electron microscopy, and metallization percentage. At 1373 K, 30 min, and I:AB = 1:2.1, the reduction of ilmenite produced TiO<sub>2</sub> and 85.6% of total iron was converted in metallic iron. Agave bagasse is transformed in the same step as ilmenite reduction, avoiding the pre-treatment of the biomass. A correlation of the experimental results with the thermodynamic data demonstrates that ilmenite reduction depends highly on the carbon generated, but the volatile matter creates porosity. Agave bagasse biomass is an excellent reducing agent for the ilmenite at short residence times, achieving a high metallization percentage. It is a substitute for carbon sources, contributing to the utilization of waste for a more sustainable process.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":17160,"journal":{"name":"Journal of Sustainable Metallurgy","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the extractive metal sector contributes to approximately 9.5% of global greenhouse gas emissions. Hydrogen gas offers a promising alternative to using carbon in metallurgical processes as an eco-friendly reductant and energy provider that produces water vapor as a by-product. However, molecular hydrogen has some barriers to implementation. These primarily concern the thermodynamics and kinetics of metal oxide reduction. To address these issues, researchers have explored the use of hydrogen plasma, which is generated by applying high energy to molecular hydrogen to produce atomic, ionic, and excited hydrogen species. Hydrogen plasma has thermodynamic and kinetic advantages over molecular hydrogen and carbon-based reductants since it exhibits a lower standard Gibbs free energy of reaction for H<sub>2</sub>O formation and a lower activation energy. Hydrogen plasma is also a versatile reductant as it is proven on a laboratory scale to produce metal in fewer steps, process a wide range of oxides feed and feed sizes, and be used to refine metals. There are, however, some limitations to using hydrogen plasma in extractive metallurgy. These include the cost of electricity, potential back reactions or reoxidation, and industrial scale-up challenges such as heat utilization or heat loss minimization. This study undertakes a comprehensive review of prior research on the use of hydrogen plasma for metal oxides reduction and reviewing state-of-the-art techniques for its use in extractive metallurgy applications. An overview of hydrogen plasma utilization for producing and refining several metals from primary or secondary feed materials, the many types of plasma reactors, and the commonly used parameters for each metal production process are also presented.

Raman spectra and X-ray diffraction patterns show that there is more well-ordered structure in carbon anodes with iron and titanium additives.

Gasification induces the anodes disordering to some extent. A detailed investigation indicates that there is a close relationship between the microstructure and anode properties. Owing to the improvement of graphitization extent, the properties of biopitch anodes with metal additives are better than that of conventional coal-tar-pitch samples, which can mitigate the adverse impact of its low coking value and amorphous structure on the density of the anodes. The catalytic graphitization mechanism is proposed for the transition of amorphous carbon to graphite structure at a lower temperature.

The method comprises generating a visualization of a blast furnace. Further, identifying a reference batch of the burden which produced hot metal of desired temperature. Further, the model provides coal rate predictions for the operators, and thus prevents the large variation in the thermal conditions of the blast furnace and provides high levels of operational stability. Current prediction model considers the real-time working state of BF and calculates the fuel requirement of the furnace thereby predicting the deviation in fuel rate from normal operating value and pinpoints the process and raw material parameters causing the deviation.

The goal of this study was to evaluate the impacts of both catalyst production as well as the recycling of spent catalyst as cobalt hydroxide, cobalt sulfate, or cobalt carbonate. Life cycle assessment (LCA) was used to quantify the environmental impacts of the studied processes. The life cycle inventory (LCI) was gathered based on the mass and energy balances of process simulations built on information available in the literature. The results show that compared to primary production of equivalent products, all studied recycling processes for spent catalyst decrease the environmental impacts by more than 50% in all investigated impact categories. For example, the global warming potential (GWP) of cobalt recovery from spent FTS catalyst as cobalt sulfate was 1.7 kg CO<sub>2</sub>-eq./kg CoSO<sub>4</sub>whereas the corresponding GWP for primary production was 4 kg CO<sub>2</sub>-eq./kg CoSO<sub>4</sub>. The process hotspots of recycling were found to be the production of the chemicals consumed, particularly sodium hydroxide and sulfuric acid, which together contributed between 64 and 95% of the total environmental impacts.
