摘要:Embodiments of the present disclosure may include the synthesis of a doped sorbent spinel material, suitable for cost-effective and industrial-scale extraction of a metal from a metal-containing fluid. Embodiments of the present disclosure further include preparing a doped precursor blend followed by calcining the doped precursor blend for optimal duration and temperature to obtain a mass of intermediate-state sorbents having constituents synthesized at desired percentages. Some embodiments may also include cooling and milling the product obtained. The doped intermediate-state sorbents include desired proportions of Mn3O4, Mn2O3, and lithium manganese oxide (LMO). In some embodiments, the doped LMO may be activated with an acid treatment. Doped LMOs obtained by the method of the present disclosure result in an enhanced loading capacity compared to undoped LMOs formed under similar temperatures and durations.

权利人:LITHOS IND INC
摘要:Embodiments of the present disclosure may include the synthesis of a sorbent spinel material, which can be essential for applications necessitating specific chemical attributes and high lithium loading capacities. The disclosure includes preparing a precursor blend from specific reactants, including manganese compounds, and calcining the precursor blend at a determined temperature and duration to form an intermediate blend with desired constituents at specific ratios. In some embodiments, cooling and milling may be performed to achieve the final product. In some embodiments the process involves adjusting the reaction conditions to bias the composition of the intermediate blend, which may include different proportions of Mn3O4, Mn2O3, and lithium manganese oxide (LMO), resulting in variable lithium loading capacities (9.0 to 23.0 mg/g of LMO) when higher-quality reactants are used.

摘要:Provided are a copper-manganese composite oxide catalyst and a preparation method therefor and a use thereof. The catalyst contains copper oxide and manganese oxide, wherein the molar ratio of the copper element to the manganese element is Cu:Mn=2:1-1:5. A synthesis method for the catalyst comprises the steps of slurry forming, grinding, spray drying and heat treatment, and the catalyst can catalyze complete oxidative decomposition of hydrocarbons, especially propane, at a low temperature. The characteristics of simple synthesis method, easy industrial scale production and low production costs are achieved, high-cost noble metal components do not require to be used, and propane can be completely oxidized into carbon dioxide and water at the lowest temperature of 400°C, without generating other by-products.
