Ruthenium Alumina Catalyst Recycling

Ruthenium iodide (RuI₃) is an inorganic compound of ruthenium, usually a dark brown or black solid. It is a ruthenium(III) compound produced by the reaction of ruthenium with iodine, and has high stability and good chemical properties. Ruthenium iodide has important applications in the field of catalysis, especially in certain redox reactions, where it can significantly improve the efficiency of reactions as a catalyst. Ruthenium iodide also plays an important role in organic synthesis and photoelectrochemical reactions. Due to its strong catalytic activity, ruthenium iodide has been widely studied and applied in high-tech fields such as electrochemistry, fuel cells, and photoelectrocatalysis. Waste ruthenium iodide is one of the raw materials for recycling ruthenium-containing precious metal catalysts. Other raw materials for recycling ruthenium-containing precious metal catalysts include recovery of ruthenium oxide, recovery of ruthenium chloride, recovery of potassium ruthenium chloride, recovery of ruthenium acetate, recovery of ruthenium trichloride, and recovery of bis(cyclopentadienyl)ruthenic acid.

Ruthenium alumina catalyst is a catalyst that combines ruthenium metal with alumina (Al2O3) support. As a carrier for ruthenium, alumina provides a larger surface area, stabilizes the dispersion of ruthenium metal, and enhances the efficiency of catalytic reactions. Ruthenium alumina catalysts are widely used in chemical reactions such as hydrogenation, catalytic cracking, oxidation reactions, and synthesis gas conversion. Ruthenium has excellent catalytic activity, especially in hydrogenation and oxidation-reduction reactions, so ruthenium alumina catalysts can effectively improve the reaction rate and selectivity. Ruthenium alumina catalysts also have important applications in the fields of petrochemicals, environmental protection, and energy, especially in gas refining and clean energy production. Waste ruthenium alumina catalysts are one of the sources for recycling ruthenium-containing precious metal catalysts. Other sources for recycling ruthenium-containing precious metal catalysts include recovery of ruthenium iodide, recovery of ruthenium chloride, recovery of potassium ruthenium chloride, recovery of ruthenium oxide, and recovery of ruthenium trichloride.

Ruthenium oxide (RuO₂) is an oxide of ruthenium, usually a black or dark brown powder, with excellent catalytic properties and stability. It is a compound formed by the oxidation of ruthenium in oxygen or air, and is commonly used in the fields of electrocatalysis, chemical reaction catalysis, and energy conversion. Ruthenium oxide is utilized as a highly efficient catalyst in reactions such as fuel cells, water electrolysis, and hydrogen production, and exhibits excellent catalytic activity and corrosion resistance, especially in the oxygen reduction reaction. Waste ruthenium oxide is one of the sources for recycling ruthenium-containing precious metal catalyst waste. Recycling of ruthenium-containing precious metal catalyst waste also includes ruthenium chloride recycling, ruthenium acetate recycling, ruthenium carbon recycling, ruthenium zinc catalyst recycling, ruthenium iodide recycling, and ruthenium aluminum oxide catalyst recycling.

Ruthenium slag refers to the solid waste or residues produced after ruthenium metal reacts with other substances during the smelting, refining, or use of ruthenium. As ruthenium is a precious metal, it is usually smelted under conditions of high temperature and pressure. Therefore, ruthenium slag often contains small amounts of other metallic impurities, such as iridium and platinum, in addition to ruthenium. The composition and properties of ruthenium slag may vary depending on the specific process by which it is produced, and it usually needs to be recovered and processed in a specific way to extract the ruthenium and other precious metals it contains. Ruthenium slag may also be used as a by-product in catalysis in some cases, or chemically processed to produce other ruthenium alloy materials. Waste ruthenium slag is one of the recycling pathways for ruthenium-containing waste. Other recycling pathways for ruthenium-containing waste include ruthenium water recycling, ruthenium slurry recycling, ruthenium slag recycling, ruthenium powder recycling, ruthenium gold recycling, ruthenium wire recycling, and ruthenium block recycling.
