Nanoparticles Used by Iranian Company to Make Sulfur Recovery Catalyst
‘Ardakan Industrial Ceramics Company (A.I.C)’ has manufactured the product which is a sulfur recovery catalyst composed of spherical ceramic nanoparticles with a high specific surface area, enjoying favorable durability in acidic and oxidant media. It is used to convert COS and CS2 compounds to H2S in the Claus process.
The application of this type of nanostructured catalyst has increased efficiency in the Claus process.
The catalyst can be used in natural gas companies, oil refining companies and coke factories.
In a relevant development in April, Iranian researchers at Amirkabir University of Technology had succeeded in recycling all three elements of vanadium, molybdenum and nickel used to produce catalysts.
“The catalysts used in the RCD unit contain about 5% to 10% of vanadium, 5% to 10% of molybdenum and 3% to 5% of nickel by weight and these metals are created as a result of absorption in the refining process of petroleum residues,” said Alireza Babayee, a PhD student at Amirkabir University of Technology.
“By conducting this research and chemical separation, we were able to produce vanadium oxide (V2O5), molybdenum oxide (MoO3) and metallic nickel (Ni) with industrial purity,” he added.
Babayee said that the technical know-how of this research can be used in the refineries that consume these used catalysts, or any company that is active in the field of recycling the used catalysts containing vanadium, molybdenum and nickel.
“On the other hand, the products can be used in alloy steel production industries,” Babayee noted.
