The primary sources of ruthenium catalysts include the petrochemical, pharmaceutical, and environmental industries. In these sectors, ruthenium catalysts are used to accelerate chemical reactions, enhancing yield and efficiency. Over time, these catalysts gradually deactivate and need to be replaced and recycled. The discarded ruthenium catalysts from industrial processes become important sources for ruthenium recovery.
Ruthenium catalysts from different sources vary in content, impurity composition, and form. Those used in the petrochemical industry contain a higher proportion of ruthenium but also have impurities like sulfur and carbon. In contrast, ruthenium catalysts in the pharmaceutical industry are more complex in form and contain a variety of organic impurities.

The disposal of spent ruthenium catalysts is typically handled by professional environmental companies. They are responsible for collecting, transporting, and processing these wastes. The core of the recycling process is to efficiently extract ruthenium from the spent catalysts.

Recycling of ruthenium catalysts generally includes steps like pretreatment, dissolution, and purification. The spent catalysts need to be incinerated or chemically treated to remove organic impurities. Then, an acidic solution is used to dissolve ruthenium from the carrier. The ruthenium in the solution can be reduced using hydrogen under certain temperatures and pressures to obtain pure metallic ruthenium.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47637.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47637.html
