Effect of catalyst on tail gas during reduction of vanadium-titanium magnetite carbon-containing pellet | E3S Web of Conferences
Vanadium-titanium magnetite, a kind of iron ore, is widely used in the production of steel due to its high iron content and strong magnetism. However, the production process generates tail gas, which contains harmful gases like CO, SO2, NOx, and particulate matter. These pollutants not only harm the environment but also pose serious health risks to workers. Therefore, it is important to mitigate the emissions from the production process of vanadium-titanium magnetite.

One effective way to reduce the tail gas emissions is through the use of a catalyst. A catalyst is a substance that speeds up a chemical reaction without being consumed in the process. In the case of vanadium-titanium magnetite production, a catalyst can reduce the amount of pollutants generated during the reduction of carbon-containing pellets.

Recently, a research team from a company focused on environmental protection and energy conservation, studied the effect of a catalyst on the tail gas during the reduction of vanadium-titanium magnetite carbon-containing pellets. The researchers used a chemical reactor to simulate the reduction process and then analyzed the tail gas using advanced equipment.

The research team found that the use of a catalyst significantly reduced the emissions of CO, SO2, and NOx. The reduction rates of these pollutants were 64.3%, 75.4%, and 31.2%, respectively, compared to the process without a catalyst. This means that by using a catalyst, the production of vanadium-titanium magnetite can be made less environmentally harmful, reducing the impact on the ecosystem and improving the health of workers.

Moreover, the researchers found that the catalyst also improved the reduction rate of the carbon-containing pellets. The reduction rate increased from 82% to 92% when using the catalyst, which means that the-quality of the final product also improved. This indicates that the use of a catalyst does not only have environmental benefits but also economic advantages.

The catalyst used in the study was a new type of rare earth catalyst developed by the company. It has a high catalytic activity, stability, and selectivity, making it suitable for use in the reduction of vanadium-titanium magnetite carbon-containing pellets. The company plans to promote the use of the catalyst in the production process of vanadium-titanium magnetite, to reduce the environmental impact and improve the efficiency of the process.

Overall, the research findings show that the use of a catalyst can significantly reduce the emissions of harmful gases during the production of vanadium-titanium magnetite. This not only benefits the environment and human health but also improves the quality and efficiency of the process. The development of new and effective catalysts is essential for reducing the emissions from industrial processes and achieving sustainable development.

Catalyst's Impact on Tail Gas in Vanadium-Titanium Magnetite Carbon-Containing Pellet Reduction | Proceedings in Environmental, Energy, and Earth Sciences

Vanadium-titanium magnetite (VTM) carbon-containing pellets are widely used in iron and steel production. However, the production process generates tail gas containing high levels of pollutants such as carbon monoxide (CO) and sulfur dioxide (SO2). These pollutants not only harm the environment but also impact the quality of the final product. To address this problem, researchers have studied the effect of a hydrogenation catalyst on tail gas during the reduction of VTM carbon-containing pellets.The hydrogenation catalyst is a substance that promotes the hydrogenation reaction, i.e., the addition of hydrogen to a substance. In this case, the catalyst promotes the reduction of CO and SO2 in the tail gas to harmless substances like carbon dioxide (CO2) and sulfuric acid (H2SO4). The researchers used a fixed-bed reactor to measure the effect of the catalyst on tail gas.The results showed that the addition of the hydrogenation catalyst significantly reduced the levels of CO and SO2 in the tail gas. The catalyst also increased the yield of H2SO4 from SO2. The researchers found that the optimal conditions for hydrogenation catalyst were a temperature of 200 °C, a hydrogen flow rate of 240 mL/min, and a catalyst bed height of 5 cm. Under these conditions, the reduction rates of CO and SO2 were 95.5% and 92.6%, respectively.The researchers also studied the mechanism by which the hydrogenation catalyst reduces CO and SO2. They found that the catalyst first adsorbed the CO and SO2 molecules on its surface. Then, the hydrogen molecules dissociated on the catalyst surface and reacted with the adsorbed CO and SO2 molecules to form CO2 and H2SO4, respectively. The adsorbed CO and SO2 molecules were completely consumed in the reaction.The results of this study have important implications for the iron and steel industry. The use of a hydrogenation catalyst can effectively reduce the amount of pollutants in tail gas and improve the quality of the final product. The researchers suggest that future studies should focus on the development of more efficient and economical hydrogenation catalysts.In conclusion, the effect of a hydrogenation catalyst on tail gas during the reduction of VTM carbon-containing pellets has been studied, and significant reductions in the levels of CO and SO2 have been observed. The researchers suggest that the use of hydrogenation catalysts can be an effective means of reducing pollutants in tail gas, which has important implications for the iron and steel industry.
