AI Technical Summary
Technical Problem
Existing SCR catalysts using silica-containing alumina binders suffer from reduced mechanical strength and structural integrity, compromising their performance.
Method used
Incorporating titanium dioxide or silica-stabilized titanium dioxide as a binder in the SCR catalyst composition, particularly in all-active extruded catalysts, enhances mechanical strength without affecting performance.
Benefits of technology
The use of titanium dioxide or silica-stabilized titanium dioxide as a binder improves mechanical strength, ensuring the catalyst maintains high performance and structural integrity, as demonstrated by increased bending strength and comparable NOX conversion rates.
