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.
