We discuss Topsoe's article that featured in the September 2025 issue of Hydrocarbon Engineering magazine. Titled ‘Guarding against silicon contamination’, this piece explores how Topsoe’s new third-generation SiliconTrap catalyst for coker naphtha can offer improved unit performance.
In this interview, we explore:
- The differences between organic and inorganic sources of silicon, and how they both impact refining operations.
- Why accurate detection of silicon type is so important.
- The main mechanisms by which silicon poisons catalysts.
- How refineries can manage against silicon poisoning.
- And much more.
