"This technology enhances production economics while supporting growth in high‑value specialty applications such as adhesives, antioxidants and performance additives."

Key Advantages for Producers:

• High‑purity isoamylene production with improved conversion and selectivity
• Reduced byproduct formation, simplifying downstream processing
• Lower energy consumption improves operating economics and reduces emissions
• Reliable, continuous operation with reduced downtime
• Flexible integration with existing units enables seamless retrofits or expansions
