The utilization of hydrogen-based direct reduction methods for magnetite ore smelting is an important way to achieve the goal of reducing carbon emissions. At present, the coupling mechanism of the ...multi-step reaction during the reduction process is unclear, which restricts the understanding of the rate-limiting steps and the accurate description of kinetic parameters. In this paper, the reaction characteristics and multi-step kinetics of isothermal reduction of magnetite by hydrogen with varying concentrations are investigated at 600–900 °C. Results indicate that the coupling relationship between Fe3O4→FeO and FeO→Fe two steps is temperature-dependent. In the low-temperature range (600–700 °C), the coupling relationship between the two steps can be described by the parallel model. In the high-temperature range (750–900 °C), the coupling relationship can be described by the series model. Meanwhile, the first-step reaction Fe3O4→FeO is controlled by the nucleation or chemical reaction model, and the apparent activation energies are determined to range from 27.25 to 48.59 kJ/mol. The second-step reaction FeO→Fe is controlled by the combination of nucleation and diffusion models, and the apparent activation energies are determined to range from 30.70 to 45.14 kJ/mol.
•Multistep kinetics of isothermal reduction of magnetite by hydrogen are studied by TGA.•The coupling relationship of two-step reduction is found to be temperature-dependent.•The parallel model and series model are used to decouple the two-step reactions in two temperature ranges respectively.•The relationship between activation energy and hydrogen concentration is obtained.

•60 % emission reduction by direct reduction of mineral iron carbonate with hydrogen.•Elevated pressure increases the degree of metallization of the reduced iron ore.•Methane fraction ...in the product gas increases with increasing reaction pressure.•Increasing feed gas flow rates result in higher methane fractions.
Direct reduction of mineral iron carbonate with hydrogen enables an over 60 % reduction of process-related CO2 emissions in iron production, compared to the conventional process route of roasting and reduction with coke. Due to the carbonaceous nature of the ore, the release of carbon-based gaseous products during reduction is inevitable. However, precise adaption of the process parameters temperature and pressure give access to a tailor-made product gas consisting of CO and methane in addition to released CO2; without compromising the product quality of the reduced iron ore.
In the present work, the effect of elevated reaction pressure (0.1–7 MPa) was investigated for different temperatures (773–973 K) and feed gas flow rates (0.0480−0.2565 m3h−1), and discussed in terms of reaction time, conversion of mineral iron carbonate, degree of metallization, and product gas composition. Elevated reaction pressure increases the degree of metallization of the reduced ore and the methane mole fraction in the product gas. The degree of metallization also increases with increasing temperature. Compared to direct reduction at ambient pressure, the degree of metallization at 2.5 MPa is significantly increased at lower temperatures. With increasing temperature, this difference becomes less evident. With an increasing feed gas flow rate, the methane mole fraction in the product gas increases.

•The direct electrochemical reduction of CO2 is realized in molten carbonate using a porous electrode.•The direct reduction is thanks to the diffusion-enhanced CO2 mass transfer.•Li- ...and alkaline earth metal-free molten carbonate reduces the cost and facilitates the downstream product separation.
Although the direct electro-reduction of CO2 is thermodynamically favorable, it is difficult to accomplish due to the limited solubility of CO2 in oxide-free molten salts. Thus, the electrochemical reduction of CO2 in molten carbonate should be assisted by the existing lithium and alkaline earth cations that alter the thermodynamic energy barrier of CO32−. In this study, we employ a porous metal foam electrode to realize the direct electro-reduction of CO2 in molten Na2CO3-K2CO3. The porous electrode increases the contact area between the solid electrode and CO2 gas, resulting in the direct electro-reduction of CO2 to CO and carbon through the thin electrolyte layer. The overall current efficiency reaches 90% for CO at 800 °C. The molten Na2CO3-K2CO3 makes the downstream product separation easy because Na2CO3 and K2CO3 are highly soluble in water. Overall, using the gas electrode achieves the direct electro-reduction of CO2 and the use of lithium- and alkaline-earth-metal-free molten carbonates, offering a more energy-efficient CO2 reduction path.
All papers published in this volume of IOP Conference Series: Materials Science and Engineering have been peer reviewed through processes administered by the Editors. Reviews were conducted by expert ...referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing. • Type of peer review: Single blind Review The detailed review process is as follows 1. Authors will submit their original and unpublished work (related to the theme of the conference). They clearly need to identify the problem, their contribution(s), and justification with respect to the state-of-the-art work. 2. Authors need to submit their papers through Easy Chair link. 3. The PC chairs will initially do the screening on the basis of scope, technical content, similarity and formatting of the submitted papers. The suitable papers will be sent for single-blind review. a. PC chairs will allow scientific committee members to choose the research topics they are willing to review. Based on this and their expertise, PC chairs will assign papers for a review manually. b. Scientific committee members can invite sub-reviewers and can hand over some papers if the papers are not within their field of expertise, and the whole process is available at the Easychair (i.e., taking help from sub reviewers). c. Scientific committee members are, however, still responsible for the quality and timeliness of the reviews allocated originally to them. Accordingly, the paper/review management system supports the allocation of reviews, at the initiation of PC members. 4. For evaluating the papers, the Easy Chair scores mechanism will be as followed: i. Strong accept (3), Accept (2) and Weak accept (1) ii. Borderline (0) iii. Strong reject (-3), Reject (-2) and Weak reject (-1) 5. In all cases, PC chairs will work closely. Based on the review reports and the scores, PC chairs send a notification to the authors via along with the review reports/scores. a. Notification is based on an average score provided by the assigned reviewers. b. Note that notification, in the first review, will be straight: accept and reject. c. The papers with an average score less than 0 will be rejected. For accepted papers, general chairs will provide a month for an additional revision, if any. This will mostly useful for those authors who have received major comments. 6. After having revised versions, we will have exactly same set of experts for review, and will add one more in case there exists contradictory review reports/scores. An example of contradictory review means giving +3 (strong accept) and -3 (strong reject) scores from two different for the same paper. At this point, PC chairs will help invite an additional reviewer. 7. After having all review reports/scores, PC chairs will make a final decision. • Conference submission management system: Easy-Chair • Number of submissions received: 75 • Number of submissions sent for review: 52 • Number of submissions accepted:23 • Acceptance Rate (Number of Submissions Accepted / Number of Submissions Received X 100): 30.66% • Average number of reviews per paper: Two • Total number of reviewers involved:51 • Any additional info on review process: NO • Contact person for queries: Dr. Girraj Sharm: girrajsharma.ece@jecrc.ac.in Dr. Ashish Kumar: ashishkumar.ece@jecrc.ac.in

•An integrated top-down and bottom-up modeling framework was developed.•Analyze low-carbon pathways for Chinese iron & steel industry towards carbon neutrality.•Both the supply-side and demand-side ...contributions to decarbonization are explored.•Energy-saving retrofitting technologies help short-term CO2 emissions reduction.•Breakthrough technologies are crucial in achieving carbon neutrality.
Iron and steel production in China contributes to 14% of China’s total energy-related CO2 emissions. Decarbonizing the iron and steel sector will therefore play an important role in achieving the goal of carbon neutrality. This study explored possible low-carbon transition pathways for China’s iron and steel industry to achieve carbon neutrality by 2050. An integrated approach was developed that combined a computable general equilibrium model and a bottom-up technology-selection module. The results indicated that although energy-saving technologies can reduce CO2 emissions in the short term, in the long term, adopting breakthrough technologies (e.g., carbon capture and storage (CCS) and hydrogen-based direct reduction (DR)), increasing the share of scrap-based electric arc furnace (EAF) steel production, and decarbonizing upstream energy-supply sectors will be crucial for climate change mitigation. Hydrogen-based DR could be an effective option for CO2 emission reduction in scenarios where CCS is not available, with its share increasing to 23%–25% by 2050. System-wide cross-sector decarbonization can help achieve climate targets at lower costs through flexible technology combinations and avoid carbon leakage into upstream energy-supply sectors.
