Spent Co-Mo/Al2O3 catalyst treated with sulfuric acid baking and leaching for improved metal recovery

A revolutionary method for the recovery of metals has been developed by scientists at the National Metallurgical Laboratory (NML) in India. Using low-temperature sulfuric acid baking followed by a mild leaching process, the researchers were able to dissolve metals from pre-oxidized refinery plant spent Co-Mo/Al2O3 catalyst. The direct sulfuric acid leaching of the same sample produced poor recoveries of aluminum and molybdenum, whereas leaching after sulfuric acid baking significantly improved the recoveries of these two metals.The pre-oxidized spent catalysts used in this study were obtained from a Korean refinery plant and found to contain 40% aluminum, 9.92% molybdenum, 2.28% cobalt, 2.5% carbon, and trace amounts of other elements such as iron, nickel, sulfur, and R XRD. The host matrix was identified to be poorly crystalline gamma-Al2O3.The researchers studied the effect of various baking parameters such as catalyst-to-acid ratio, baking temperature, and baking time on the percentage dissolution of metals. They observed that the dissolution of metals increases with an increase in the baking temperature up to 300 degrees Celsius, after which it decreases with further increases in the baking temperature. Under optimum baking conditions, more than 90% of cobalt and molybdenum, and 93% of aluminum could be dissolved from the spent catalyst with the following leaching conditions: H2SO4 = 2% (v/v), temperature = 95 degrees Celsius, time = 60 minutes, and pulp density = 5%.This method has the potential to revolutionize the metal recovery industry by offering a more efficient and cost-effective process for the recovery of valuable metals from spent catalysts. This will also reduce the negative impact of spent catalysts on the environment, as they will no longer have to be disposed of in landfills.The NML is one of India's leading research institutes in the field of metallurgy, materials science, and engineering, and this discovery demonstrates its ongoing commitment to advancing the field.

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. The keywords "Tail Gas Hydrogenation Catalyst" may help promote this research and enhance its academic influence.

Mechanistic Insights into DME Conversion over ZSM-5 Catalysts

and Dimethyl Ether (DME)ZSM-5 catalysts play a significant role in the conversion of dimethyl ether (DME) to olefins. This reaction is an important step in the production of valuable chemical compounds. However, the mechanism of this transformation has been elusive due to the complex nature of the reaction. In a recent study, researchers used temperature-programmed surface reaction experiments and microkinetic modelling to decouple the rates of adsorption, desorption, and surface reaction of DME over fresh and working ZSM-5 catalysts with different Si/Al ratios.The study yielded important insights into the reaction mechanism. The researchers discovered that propylene is the major olefin formed during the transformation of DME. They also observed site-specific scaling relations between the activation energies of DME desorption and barriers to the formation of methoxymethyl and methyl propenyl ether. Six ensembles of sites were observed, with a maximum of three adsorption/desorption sites and three adsorption/desorption/reaction sites.Interestingly, the researchers found that barriers were generally higher for working catalysts than fresh catalysts. This could have implications for industrial processes that use ZSM-5 catalysts.The study’s results were obtained by simulating transient reactor performance through the solving of coupled 1D nonlinear partial differential equations. This accounted for elementary steps during the induction period, based on the methoxymethyl mechanism on the zeolite catalyst, and axial dispersion and convection in the reactor. The activation energies of propylene formation were found to be approximately 200 kJ mol1, which corroborated direct mechanistic proposals.Overall, this study provides valuable mechanistic insights into the conversion of DME over ZSM-5 catalysts. The researchers’ use of temperature-programmed surface reaction experiments and microkinetic modelling allowed for decoupling the complex rates of the reaction, providing important information about site-specific mechanisms. This information may prove useful for developing more efficient and effective industrial processes that utilize ZSM-5 catalysts.In conclusion, the study underscores the importance of understanding the mechanistic details of catalytic reactions. By using advanced experimental and modelling techniques, we can gain insights that will allow for the development of more efficient and sustainable industrial processes.

One industry that is leading the way in this endeavor is the cement production industry. This industry has long been known for its high levels of carbon emissions and is actively seeking ways to reduce them. One of the latest and most promising technologies in the field is zeolite catalyst technology, which has been developed by Clariant Catalyst Technology.Cement production is an energy-intensive process that accounts for around 8% of global CO2 emissions. As such, finding ways to reduce these emissions is a priority for the industry. The traditional cement production process involves the mining of raw materials, such as limestone, clay, and shale. These materials are then ground into a fine powder, which is mixed with water and other additives to create a raw meal. This meal is then heated in a kiln at extremely high temperatures, producing clinker, which is then ground again to create the final product. In this process, large amounts of heat are needed, which is traditionally produced through the burning of fossil fuels, which results in carbon emissions.With zeolite catalyst technology, however, it is possible to reduce these emissions drastically. This technology involves the use of a catalyst that is added to the raw meal during the production process. This catalyst acts as a catalyst for the chemical reactions that take place during the cement production process. By using this catalyst, the temperature at which the raw meal is heated can be greatly reduced, resulting in significantly lower carbon emissions.One of the key benefits of Clariant Catalyst Technology's zeolite catalyst technology is that it can be used in existing cement production plants without requiring any major modifications. This makes it easy for companies to adopt this technology, allowing for a smooth and quick transition to cleaner production methods. Additionally, this technology can also help to increase the efficiency of cement production, reducing the amount of energy needed per ton of cement produced.Another benefit of zeolite catalyst technology is that it can help cement producers to comply with increasingly strict environmental regulations. As governments around the world tighten their carbon emissions regulations, the cement industry has been under pressure to find ways to reduce their emissions. By using this technology, cement producers can reduce their emissions and avoid costly fines and penalties.Finally, the use of zeolite catalyst technology can also help cement producers to improve their reputation and appeal to environmentally conscious consumers. As consumers become more aware of the impact of their purchasing decisions on the environment, they are seeking out products that are produced in an environmentally responsible way. By adopting cleaner production technologies such as this, cement producers can appeal to this growing market segment and differentiate themselves from their competitors.In conclusion, Clariant Catalyst Technology's zeolite catalyst technology is an exciting development in the cement production industry. By reducing carbon emissions, increasing efficiency, and helping producers to comply with regulations, this technology is helping to create a more sustainable future for the industry.
